Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation Our consolidated financial statements include the accounts of Delek and its subsidiaries. All significant intercompany transactions and account balances have been eliminated in consolidation. We have evaluated subsequent events through the filing of this Form 10-K. Any material subsequent events that occurred during this time have been properly recognized or disclosed in our financial statements. Our consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics", NYSE:DKL), which is a variable interest entity ("VIE"). As the indirect owner of the general partner of Delek Logistics, we have the ability to direct the activities of this entity that most significantly impact its economic performance. We are also considered to be the primary beneficiary for accounting purposes for this entity and are Delek Logistics' primary customer. As Delek Logistics does not derive an amount of gross margin material to us from third parties, there is limited risk to Delek associated with Delek Logistics' operations. However, in the event that Delek Logistics incurs a loss, our operating results will reflect such loss, net of intercompany eliminations, to the extent of our ownership interest in this entity. The preparation of financial statements in conformity with United States ("U.S.") Generally Accepted Accounting Principles ("GAAP") and in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments necessary for a fair presentation of the financial condition and the results of operations have been included. All adjustments are of a normal, recurring nature. Reclassifications Certain immaterial reclassifications have been made to prior period presentation in order to conform to the current year presentation. Risks and Uncertainties Arising from the COVID-19 Pandemic U.S. economic activity has continued on a recovery trend during the year ended December 31, 2021, albeit remaining subject to heightened levels of uncertainty related to the on-going impact of the COVID-19 outbreak that developed into a pandemic in March 2020 (the “COVID-19 Pandemic” or the “Pandemic”), and the spread of new variants of the virus. Most of the restrictions imposed in the prior year to prevent its spread have been eased and government vaccination campaigns continue. Compared to the prior year, the economic recovery trends in the year ended December 31, 2021 included a resumption of flights by major airlines and increased motor vehicle use. This has in turn resulted in increased demand and market prices for crude oil and certain of our products. Nonetheless, there remains continued uncertainty about the duration and future impact of the COVID-19 Pandemic. Uncertainties related to the impact of the COVID-19 Pandemic and other events exist that could impact our future results of operations and financial position, the nature of which and the extent to which are currently unknown. To the extent these uncertainties have been identified and are believed to have had a material impact on our current period results of operations or financial position based on the requirements for assessing such financial statement impact under GAAP, we have considered them in the preparation of our consolidated financial statements as of and for the year ended December 31, 2021. The application of accounting policies impacted by such considerations include (but are not necessarily limited to) the following: • The evaluation of indefinite-lived intangibles and goodwill for potential impairment during our annual assessment or where indicators exist, as defined by GAAP; • The evaluation of long-lived assets for potential impairment, where indicators exist, as defined by GAAP; • The evaluation of joint ventures for potential impairment, where indicators exist, as defined by GAAP; • The evaluation of derivatives and hedge accounting for counterparty risk and changes in forecasted transactions, as provided for under GAAP; • The evaluation of inventory valuation allowances that may be warranted under the lower of cost or net realizable value analysis, for first-in, first-out (“FIFO”), and the lower of cost or market analysis, for last-in, first-out ("LIFO"), pursuant to GAAP; • The consideration of debt modifications and/or covenant requirements, as applicable; • The evaluation of commitments and contingencies, including changes in concentrations, as applicable; • The evaluation of the impact of changing forecasts on our assessment of deferred tax asset valuation allowances and annual effective tax rates; and • The evaluation of our ability to continue as a going concern. Segment Reporting Delek is an integrated downstream energy business based in Brentwood, Tennessee, and has three primary lines of business: petroleum refining; the transportation, storage and wholesale distribution of crude oil, intermediate and refined products; and convenience store retailing. For the periods presented, we have aggregated our operating segments into three reportable segments: Refining, Logistics and Retail. Operations that are not specifically included in the reportable segments are included in Corporate, Other and Eliminations, which consists of the following: • our corporate activities; • results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 11); • wholesale crude operations • Alon's asphalt terminal operations acquired as part of the Delek/Alon Merger; • results and assets of discontinued operations; and • intercompany eliminations. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of the reportable segments based on the segment contribution margin. Segment contribution margin is defined as net revenues less cost of materials and other and operating expenses, excluding depreciation and amortization. All inter-segment transactions have been eliminated in consolidation. The refining segment operates high conversion, independent refineries located in Tyler, Texas (the "Tyler refinery"), El Dorado, Arkansas (the "El Dorado refinery"), Big Spring, Texas (the "Big Spring refinery"), Krotz Springs, Louisiana (the "Krotz Springs refinery"). In addition, the refining segment owns and operates three biodiesel facilities involved in the production of biodiesel fuels and related activities, located in Crossett, Arkansas, Cleburne, Texas and New Albany, Mississippi. The logistics segment owns and operates crude oil and refined products logistics and marketing assets. The retail segment markets gasoline, diesel and other refined petroleum products, and convenience merchandise through a network of company-operated retail fuel and convenience stores. Segment reporting is more fully discussed in Note 3. Cash and Cash Equivalents Delek maintains cash and cash equivalents in accounts with large, U.S. or multi-national financial institutions. All highly liquid investments purchased with a term of three months or less are considered to be cash equivalents. As of December 31, 2021 and 2020, these cash equivalents consisted primarily of bank money market accounts and bank certificates of deposit, as well as overnight investments in U.S. Government or its agencies' obligations and bank repurchase obligations collateralized by U.S. Government or its agencies' obligations. Accounts Receivable Accounts receivable primarily consists of trade receivables generated in the ordinary course of business, but may also include receivables on commodity sales contracts that are part of crude optimization and are, therefore, related to transactions that are reflected as reductions of cost of materials and other rather than revenue. Such other receivables are with the same or similar customers as our trade receivables, and are subject to the same characteristics regarding the nature, timing, pricing and risk. Delek recorded an allowance for doubtful accounts related to accounts receivable of $6.5 million and $7.2 million as of December 31, 2021 and 2020, respectively. Credit is extended based on evaluation of the customer’s financial condition. We perform ongoing credit evaluations of our customers and require letters of credit, prepayments or other collateral or guarantees as management deems appropriate. Allowance for doubtful accounts is based on a combination of historical experience and specific identification methods. Credit risk is minimized as a result of the ongoing credit assessment of our customers and a lack of concentration in our customer base. Credit losses are charged to allowance for doubtful accounts when deemed uncollectible. Our allowance for doubtful accounts is reflected as a reduction of accounts receivable in the consolidated balance sheets. One customer accounted for more than 10% of our consolidated accounts receivable balance as of December 31, 2021 and 2020. No customer accounted for more than 10% of consolidated net sales for the years ended December 31, 2021, 2020 or 2019. Inventory Refinery crude oil, work-in-process, refined products, blendstocks and asphalt inventory for all of our operations, excluding the Tyler refinery and merchandise inventory in our Retail segment, are stated at the lower of cost determined using the FIFO basis or net realizable value. Cost of inventory at the Tyler refinery is determined using the LIFO inventory valuation method and inventory is stated at the lower of LIFO cost or market. Retail merchandise inventory consists of cigarettes, beer, convenience merchandise and food service merchandise and is stated at estimated cost as determined by the retail inventory method. We are not subject to concentration risk with specific suppliers, since our crude oil and refined products inventory purchases are commodities that are readily available from a large selection of suppliers. Investment Commodities Investment commodities represent those commodities (generally crude oil) physically on hand as a result of trading activities with physical forward contracts where such crude will not be used (either directly in production or indirectly through inventory optimization) in the normal course of our refining business. Such investment commodities are maintained on a weighted average cost basis for determining realized gains and losses on physical purchases and sales under forward contracts, and ending balances are adjusted to fair value at each reporting date using published market prices of the commodity on the applicable exchange. The investment commodities are included in other current assets on the accompanying consolidated balance sheets and changes in fair value are recorded in other operating income in the accompanying consolidated statements of income. Property, Plant and Equipment Assets acquired by Delek in conjunction with business acquisitions are recorded at estimated fair value at the acquisition date in accordance with the purchase method of accounting as prescribed in Accounting Standards Codification ("ASC") 805, Business Combinations ("ASC 805"). Other acquisitions of property and equipment are carried at cost. Betterments, renewals and extraordinary repairs that extend the life of an asset are capitalized. Maintenance and repairs are charged to expense as incurred. Delek owns certain fixed assets on leased locations and depreciates these assets and asset improvements over the lesser of management's estimated useful lives of the assets or the remaining lease term. Depreciation is computed using the straight-line method over management's estimated useful lives of the related assets, which are as follows: Years Building and building improvements 15-40 Refinery machinery and equipment 5-40 Pipelines and terminals 15-40 Retail store equipment and site improvements 7-40 Refinery turnaround costs 4-6 Automobiles 3-5 Computer equipment and software 3-10 Furniture and fixtures 5-15 Asset retirement obligation assets 15-50 Other Intangible Assets Other intangible assets acquired in a business combination and determined to be finite-lived are amortized over their respective estimated useful lives. The finite-lived intangible assets are amortized on straight-line basis over the estimated useful lives of five Property, Plant and Equipment and Other Intangibles Impairment Property, plant and equipment held and used and other intangibles are evaluated for impairment whenever indicators of impairment exist. In accordance with ASC 360, Property, Plant and Equipmen t ("ASC 360") and ASC 350, Intangibles - Goodwill and Other ("ASC 350"), Delek evaluates the realizability of these long-lived assets as events occur that might indicate potential impairment. In doing so, Delek assesses whether the carrying amount of the asset is recoverable by estimating the sum of the future cash flows expected to result from the asset, undiscounted and without interest charges. If the carrying amount is more than the recoverable amount, an impairment charge must be recognized based on the fair value of the asset. These impairment charges are included in other operating income in our consolidated statements of income. There were no impairment charges for the years ended December 31, 2021, 2020 or 2019. Equity Method Investments For equity investments that are not required to be consolidated under the variable or voting interest model, we evaluate the level of influence we are able to exercise over an entity’s operations to determine whether to use the equity method of accounting. Our judgment regarding the level of influence over an equity method investment includes considering key factors such as our ownership interest, participation in policy-making and other significant decisions and material intercompany transactions. Equity investments for which we determine we have significant influence are accounted for as equity method investments. Amounts recognized for equity method investments are included in equity method investments in our consolidated balance sheets and adjusted for our share of the net earnings and losses of the investee and cash distributions, which are separately stated in our consolidated statements of income and our consolidated statements of cash flows. We evaluate our equity method investments presented for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired. There were no impairment losses recorded on equity method investments for the years ended December 31, 2021, 2020 or 2019. See Note 6 for further information on our equity method investments. Variable Interest Entities Our consolidated financial statements include the financial statements of our subsidiaries and variable interest entities, of which we are the primary beneficiary. We evaluate all legal entities in which we hold an ownership or other pecuniary interest to determine if the entity is a VIE. Variable interests can be contractual, ownership or other pecuniary interests in an entity that change with changes in the fair value of the VIE’s assets. If we are not the primary beneficiary, the general partner or another limited partner may consolidate the VIE, and we record the investment as an equity method investment. Capitalized Interest Delek capitalizes interest on capital projects associated with the refining and logistics segments. Refinery Turnaround Costs Refinery turnaround costs are incurred in connection with planned shutdowns and inspections of our refineries' major units to perform necessary repairs and replacements. Refinery turnaround costs are deferred when incurred, classified as property, plant and equipment and amortized on a straight-line basis over that period of time estimated to lapse until the next planned turnaround occurs. Refinery turnaround costs include, among other things, the cost to repair, restore, refurbish or replace refinery equipment such as vessels, tanks, reactors, piping, rotating equipment, instrumentation, electrical equipment, heat exchangers and fired heaters. Goodwill and Impairment Goodwill in an acquisition represents the excess of the aggregate purchase price over the fair value of the identifiable net assets. Goodwill is reviewed at least annually during the fourth quarter for impairment, or more frequently if indicators of impairment exist, such as disruptions in our business, unexpected significant declines in operating results or a sustained market capitalization decline. Goodwill is evaluated for impairment by comparing the carrying amount of the reporting unit to its estimated fair value. In accordance with ASU 2017-04, Goodwill and Other (Topic 350); Simplifying the Test for Goodwill Impairment , a goodwill impairment charge is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. In assessing the recoverability of goodwill, assumptions are made with respect to future business conditions and estimated expected future cash flows to determine the fair value of a reporting unit. We may consider inputs such as a market participant weighted average cost of capital, gross margin, capital expenditures and long-term growth rates based on historical information and our best estimate of future forecasts, all of which are subject to significant judgment and estimates. We may also consider a market approach in determining or corroborating the fair values of the reporting units using a multiple of expected future cash flows, such as those used by third-party analysts, which is also subject to significant judgment and estimates. If these estimates and assumptions change in the future, due to factors such as a decline in general economic conditions, competitive pressures on sales and margins and other economic and industry factors beyond management's control, an impairment charge may be required. A significant risk to our future results and the potential future impairment of goodwill is the volatility of the crude oil and the refined product markets which is often unpredictable and may negatively impact our results of operations in ways that cannot be anticipated and that are beyond management's control. Our annual assessment of goodwill resulted in an impairment of $126.0 million during the year ended December 31, 2020. There was no impairment during the years ended December 31, 2021 and 2019, respectively. Details of remaining goodwill balances by segment are included in Note 17. Derivatives Delek records all derivative financial instruments, including any interest rate swap and cap agreements, fuel-related derivatives, over the counter ("OTC") future swaps, forward contracts and future RIN purchase and sales commitments that qualify as derivative instruments, at estimated fair value in accordance with the provisions of ASC 815, Derivatives and Hedging ("ASC 815"). Changes in the fair value of the derivative instruments are recognized in operations, unless we elect to apply and qualify for the hedging treatment permitted under the provisions of ASC 815 allowing such changes to be classified as other comprehensive income for cash flow hedges. We determine the fair value of all derivative financial instruments utilizing exchange pricing and/or price index developers such as Platts, Argus or OPIS. On a regular basis, Delek enters into commodity contracts with counterparties for the purchase or sale of crude oil, blendstocks, and various finished products. We evaluate these contracts under ASC 815 and do not measure at fair value if they qualify for, and we elect, the normal purchase / normal sale ("NPNS") exception. Delek's policy under the guidance of ASC 815-10-45, Derivatives and Hedging - Other Presentation Matters ("ASC 815-10-45"), is to net the fair value amounts recognized for multiple derivative instruments executed with the same counterparty and offset these values against the cash collateral arising from these derivative positions. Fair Value of Financial Instruments The fair values of financial instruments are estimated based upon current market conditions and quoted market prices for the same or similar instruments. Management estimates that the carrying value approximates fair value for all of Delek's assets and liabilities that fall under the scope of ASC 825, Financial Instruments ("ASC 825"). Delek also applies the provisions of ASC 825 as it pertains to the fair value option with respect to certain financial instruments. This option permits the election to carry financial instruments and certain other items similar to financial instruments at fair value on the balance sheet, with all changes in fair value reported in earnings. Delek applies the provisions of ASC 820, Fair Value Measurements and Disclosure ("ASC 820"), which defines fair value, establishes a framework for its measurement and expands disclosures about fair value measurements. ASC 820 applies to our commodity and other derivatives that are measured at fair value on a recurring basis, and to our supply and offtake agreements and environmental credit obligations that are accounted for under the fair value election. ASC 820 also applies to the measurement of our equity method investment, goodwill and long-lived tangible and intangible assets when determining whether or not an impairment exists, when circumstances require evaluation. This standard also requires that we assess the impact of nonperformance risk on our derivatives. Nonperformance risk is not considered material to our financial statements as of December 31, 2021 and 2020. Inventory Supply and Offtake Obligations Delek has Supply and Offtake Agreements (the "Supply and Offtake Agreements" or the "J. Aron Agreements") with J. Aron & Company ("J. Aron") in connection with its El Dorado, Big Spring and Krotz Springs refineries, which provide a financing mechanism on contractual baseline inventory volumes and also revolving over and short volumes. We account for the market-indexed obligations under our Supply and Offtake Agreements as product (in this case, crude oil and refined product inventory) financing arrangements under the fair value option pursuant to ASC 825 and the fair value guidance provided by ASC 820, and recognize all changes in the fair value in cost of materials and other in the accompanying statements of income. During periods where we had fixed price components that were subject to interest rate risk and not market price risk, the changes in fair value of those components was recognized in interest expense. By electing the fair value option, the changes in fair value provide a natural economic hedge to our FIFO cost of sales recognition without having to bifurcate any embedded derivatives and consider the complex hedge accounting rules. See Notes 9 and 12 for further discussion. Environmental Credits and Related Regulatory Obligations As part of our refining operations, we generate certain regulatory environmental credit obligations due to the U.S. Environmental Protection Agency (“EPA”) or other regulatory agencies. Additionally, we may generate, during the operation of our refining or other activities, or purchase on a market, environmental credits for purposes of ultimately meeting expected environmental credit obligations. These resultant net environmental credit obligations are financial instruments under ASC 825. For those financial instruments where (1) there are consistently available observable market inputs or market-corroborated inputs; and (2) there continues to be (or is reasonably expected to be) sustained liquidity in the applicable credits market, we generally apply the fair value option, as available pursuant to ASC 825. We recognize a current liability at the end of each reporting period in which we do not have sufficient environmental credits to cover the current environmental credits obligation (a “deficit”), and we recognize a current asset at the end of each reporting period in which we have generated or acquired environmental credits meeting our recognition criteria in excess of our current environmental credits obligation (a “surplus”). Any obligation surplus or deficit would be measured at fair value either directly through the observable inputs or indirectly through the market-corroborated inputs. The net cost of environmental credits used each period as well as changes to fair value attributable to our environmental credit obligations (surplus or deficit) are charged to cost of materials and other in the consolidated statements of income. Our environmental credit obligations predominantly relate to EPA’s Renewable Fuel Standard - 2 ("RFS-2"), which requires that certain refiners generate environmental credits, called Renewable Identification Numbers ("RINs"), by blending renewable fuels into the fuel products they produce, or else purchasing RINs on the market, and that such RINs shall be used to satisfy the related environmental credit obligation. Each of our refineries is an obligated party under RFS-2. To the extent that any of our refineries is unable to blend or produce renewable fuels to or generate or obtain sufficient RINs, it must purchase RINs to satisfy its annual requirement ("RINs Obligation"). To the extent that we have purchased RINs or transferred RINs to our refineries, each refinery’s RINs Obligation may be a surplus or deficit at the end of each reporting period (their respective “Net RINs Obligation”). Because our Net RINs Obligations exceed the RINs we are able to generate annually on a consolidated basis, and because we have the legal ability to transfer RINs generated or purchased through any of our entities to our obligated parties as needed, we view and manage the Company’s individual Net RINs Obligations, as well as any non-obligated party RINs holdings, on a consolidated basis. Therefore, the sum of our individual obligated parties’ Net RINs Obligations as well as RINs held by our non-obligated parties which meet our recognition criteria, comprises the Company’s “Consolidated Net RINs Obligation.” For all periods presented in these consolidated financial statements, the individual financial instruments relating to specific category and vintage requirements under RFS-2 comprising our Consolidated Net RINs Obligation are subject to market risk and meet the criteria set forth above. Therefore, we have elected to apply the fair value option to the individual financial instruments comprising our Consolidated Net RIN Obligation, using the fair value guidance provided by ASC 820. Recognition of production-related RINs Obligation expense reflects the accrual of our RINs Obligation based on the current period production using current market price of RINs. We record fair value adjustments to the RINs Obligation to reflect the ending market price of the underlying RINs relating to RINs Obligation incurred on previous production that is still outstanding. We also may have changes in fair value attributable to changes in other observable market inputs, such as changes in volumetric expectations for obligation years where the volumetric rates have not yet been enacted. Therefore, fair value adjustments represent adjustments for changes in observable inputs from what they were when we initially incurred and recorded the obligation. Other Related Transactions From time to time, Delek enters into future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our RINs Obligation. These future RINs commitment contracts meet the definition of derivative instruments under ASC 815, and are measured at fair value based on quoted prices from an independent pricing service. Changes in the fair value of these future RINs commitment contracts are recorded in cost of materials and other on the consolidated statements of income. See Note 11 for further information. Additionally, from time to time, we may elect to sell surplus environmental credits and contemporaneously enter into a corresponding obligation to repurchase substantially identical environmental credits at a future date to provide an additional source of short-term financing and to take advantage of market liquidity for holdings that are not currently required for operations. We account for such transactions as product financing arrangements. In such cases, the sale is not recognized, but rather the proceeds are treated as product financing proceeds where a corresponding product financing obligation is recorded, while the subsequent repurchase is treated as repayment of the product financing obligation, with the difference recorded as interest expense over the intervening period. Such transactions are included in our cash flows from financing transactions. Self-Insurance Reserves Delek has varying deductibles or self-insured retentions on our workers’ compensation, general liability, automobile liability insurance and medical claims for certain employees with coverage above the deductibles or self-insured retentions in amounts management considers adequate. We maintain an accrual for these costs based on claims filed and an estimate of claims incurred but not reported. Differences between actual settlements and recorded accruals are recorded in the period identified. Environmental Expenditures It is Delek's policy to accrue environmental and clean-up related costs of a non-capital nature when it is both probable that a liability has been incurred and the amount can be reasonably estimated. Environmental liabilities represent the current estimated costs to investigate and remediate contamination at sites where we have environmental exposure. This estimate is based on assessments of the extent of the contamination, the selected remediation technology and review of applicable environmental regulations, typically considering estimated activities and costs for 15 years, and up to 30 years if a longer period is believed reasonably necessary. Such estimates may require judgment with respect to costs, time frame and extent of required remedial and clean-up activities. Accruals for estimated costs from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study and include, but are not limited to, costs to perform remedial actions and costs of machinery and equipment that are dedicated to the remedial actions and that do not have an alternative use. Such accruals are adjusted as further information develops or circumstances change. We discount environmental liabilities to their present value if payments are fixed or reliably determinable. Expenditures for equipment necessary for environmental issues relating to ongoing operations are capitalized. Provisions for environmental liabilities generally are recognized in operating expenses. Changes in laws and regulations and actual remediation expenses compared to historical experience could significantly impact our results of operations and financial position. We believe the estimates selected, in each instance, represent our best estimate of future outcomes, but the actual outcomes could differ from the estimates selected. Asset Retirement Obligations Delek initially recognizes liabilities which represent the fair value of a legal obligation to perform asset retirement activities, including those that are conditional on a future event, when the amount can be reasonably estimated. If a reasonable estimate cannot be made at the time the liability is incurred, we record the liability when sufficient information is available to estimate the liability’s fair value. In the refining segment, we have asset retirement obligations with respect to our refineries due to various legal obligations to clean and/or dispose of these assets at the time they are retired. In the logistics segment, these obligations relate to the required cleanout of the pipeline and terminal tanks and removal of certain above-grade portions of the pipeline situated on right-of-way property. In the retail segment, we have asset retirement obligations related to the removal of underground storage tanks and the removal of brand signage at owned and leased retail sites which

Segment Reporting [Abstract]
Segment Data	Segment Data We aggregate our operating segments into three reportable segments: Refining, Logistics and Retail. Operations that are not specifically included in the reportable segments are included in Corporate, Other and Eliminations, which consists of the following: • our corporate activities; • results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 11); • wholesale crude operations; • Alon's asphalt terminal operations; • our discontinued Paramount and Long Beach, California refinery and California renewable fuels facility operations (acquired as part of the Delek/Alon Merger) (see Note 7 for further discussion); and • intercompany eliminations. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of the reportable segments based on the segment contribution margin. During the first quarter of 2020, we revised the structure of the internal financial information reviewed by management and began allocating the results of hedging activity associated with managing risks of our refineries, previously reported in corporate, other and eliminations, to our refining segment. Refining Segment The refining segment processes crude oil and other feedstocks for the manufacture of transportation motor fuels, including various grades of gasoline, diesel fuel and aviation fuel, asphalt and other petroleum-based products that are distributed through owned and third-party product terminals. The refining segment has a combined nameplate capacity of 302,000 barrels per day ("bpd") as of December 31, 2021, including the following: • 75,000 bpd Tyler, Texas refinery; • 80,000 bpd El Dorado, Arkansas refinery; • 73,000 bpd Big Spring, Texas refinery; and • 74,000 bpd Krotz Springs, Louisiana refinery. As of December 31, 2021, the refining segment also owns and operates three biodiesel facilities involved in the production of biodiesel fuels and related activities, located in Crossett, Arkansas, Cleburne, Texas and New Albany, Mississippi. The biodiesel industry has historically been substantially aided by federal and state tax incentives. One tax incentive program that has been significant to our renewable fuels facilities is the federal blender's tax credit (also known as the biodiesel tax credit or "BTC"). The BTC provides a $1.00 refundable tax credit per gallon of pure biodiesel to the first blender of biodiesel with petroleum-based diesel fuel. The blender's tax credit was re-enacted in December 2019 for the years 2020 through 2022 and was retroactively reinstated for 2019. On May 7, 2020, we sold our equity interests in Alon Bakersfield Property, Inc., an indirect wholly-owned subsidiary that owns the non-operating refinery located in Bakersfield, California, to a subsidiary of Global Clean Energy Holdings, Inc. (“GCE”) for total cash consideration of $40.0 million. As a result of this sale, we recognized a gain of $56.8 million, largely due to the buyer assuming substantially all of the asset retirement obligations and environmental liabilities associated with this refinery, which is included in gain on sale of non-operating refinery on the accompanying consolidated statements of income. As part of the transaction, GCE granted a call option to Delek to acquire up to a 33 1/3% limited member interest in the acquiring subsidiary of GCE for up to $13.3 million, subject to certain adjustments. Such option is exercisable by Delek through the 90th day after GCE demonstrates commercial operations, as contractually defined which has not yet occurred as of December 31, 2021. The refining segment's petroleum-based products are marketed primarily in the south central, southwestern and western regions of the United States. This segment also ships and sells gasoline into wholesale markets in the southern and eastern United States. Motor fuels are sold under the Alon or Delek brand through various terminals to supply Alon or Delek branded retail sites. In addition, Alon sells motor fuels through its wholesale distribution network on an unbranded basis. Logistics Segment Our logistics segment owns and operates crude oil and refined products logistics and marketing assets. The logistics segment generates revenue by charging fees for gathering, transporting and storing crude oil and for marketing, distributing, transporting and storing intermediate and refined products in select regions of the southeastern United States and West Texas for our refining segment and third parties, and sales of wholesale products in the West Texas market. Retail Segment Our retail segment includes the operations of owned and leased convenience store sites located primarily in West Texas and New Mexico. These convenience stores typically offer various grades of gasoline and diesel under the Alon or Delek brand name and food products, food service, tobacco products, non-alcoholic and alcoholic beverages, general merchandise as well as money orders to the public, primarily under the 7-Eleven and DK or Alon brand names. Substantially all of the motor fuel sold through our retail segment is supplied by our Big Spring refinery, which is transferred to the retail segment at prices substantially determined by reference to published commodity pricing information. We operated 248 and 253 stores as of December 31, 2021 and 2020, respectively. In November 2018, we terminated the license agreement with 7-Eleven, Inc. The terms of such agreement and subsequent amendments require the removal of all 7-Eleven branding on a store-by-store basis by December 31, 2023. Merchandise sales at our convenience store sites will continue to be sold under the 7-Eleven brand name until 7-Eleven branding is removed at such convenience store sites.

Earnings Per Share [Abstract]
Earnings Income (Loss) Per Share	Earnings Income (Loss) Per Share Earnings Income (Loss) Per Share Basic earnings per share (or "EPS") is computed by dividing net income (loss) by the weighted average common shares outstanding. Diluted earnings per share is computed by dividing net income (loss), as adjusted for changes to income that would result from the assumed settlement of the dilutive equity instruments included in diluted weighted average common shares outstanding, by the diluted weighted average common shares outstanding. For all years presented, we have outstanding various equity-based compensation awards that are considered in our diluted EPS calculation (when to do so would not be anti-dilutive), and is inclusive of awards disclosed in Note 20 to these consolidated financial statements. For those instruments that are indexed to our common stock, they are generally dilutive when the market price of the underlying indexed share of common stock is in excess of the exercise price. The following table sets forth the computation of basic and diluted earnings per share.

Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract]
Delek Logistics	Delek Logistics Delek Logistics Delek Logistics is a publicly traded limited partnership that was formed by Delek in 2012 to own, operate, acquire and construct crude oil and refined products logistics and marketing assets. A substantial majority of Delek Logistics' assets are integral to Delek’s refining and marketing operations. As of December 31, 2021, we owned a 79.8% interest in Delek Logistics, consisting of 34,696,800 common limited partner units and the non-economic general partner interest. The limited partner interests in Delek Logistics not owned by us are reflected in net income attributable to non-controlling interest in the accompanying consolidated statements of income and in non-controlling interest in subsidiaries in the accompanying consolidated balance sheets. On December 20, 2021, Delek commenced a program to sell up to 434,590 common limited partner units representing limited partner interests in Delek Logistics over the next three months in open market transactions conducted pursuant to Rule 144 under the Securities Act of 1933, as amended, and a Rule 10b5-1 trading plan. As of December 31, 2021, we have sold 49,068 units for gross proceeds of $2.1 million; $1.7 million net of taxes. On August 13, 2020, Delek Logistics completed a transaction to eliminate the IDRs held by Delek Logistics GP, LLC ("Logistics GP"), the general partner, and convert the 2.0% economic general partner interest into a non-economic general partner interest in exchange for total consideration consisting of $45.0 million cash and 14.0 million newly issued common limited partner units. Contemporaneously, we repurchased the 5.2% ownership interest in the general partner from affiliates, who were also members of the general partner's management and board of directors, for $23.1 million, increasing our ownership interest in the general partner to 100.0%. As a result of these transactions, the non-controlling interest in our consolidated balance sheets decreased by $50.8 million, with a $37.2 million increase to additional paid-in capital which is net of $11.5 million related to deferred income taxes and $2.1 million of transaction costs. In August 2020, Delek Logistics filed a shelf registration statement, which subsequently became effective, with the U.S. Securities and Exchange Commission for the proposed re-sale or other disposition from time to time by Delek of up to 14.0 million common limited partner units representing our limited partner interests in Delek Logistics. No units were sold for the year ended December 31, 2021. We have agreements with Delek Logistics that, among other things, establish fees for certain administrative and operational services provided by us and our subsidiaries to Delek Logistics, provide certain indemnification obligations and establish terms for fee-based commercial logistics and marketing services provided by Delek Logistics and its subsidiaries to us. The revenues and expenses associated with these agreements are eliminated in consolidation. Delek Logistics is a VIE, as defined under GAAP, and is consolidated into our consolidated financial statements, representing our logistics segment. The assets of Delek Logistics can only be used to settle its own obligations and its creditors have no recourse to our assets. Exclusive of intercompany balances and the marketing agreement intangible asset between Delek Logistics and Delek which are eliminated in consolidation, the Delek Logistics consolidated balance sheets are included in the consolidated balance sheets of Delek. The Delek Logistics consolidated balance sheets are presented below (in millions): December 31, 2021 2020 ASSETS Cash and cash equivalents $ 4.3 $ 4.2 Accounts receivable 15.4 15.7 Accounts receivable from related parties — 5.9 Inventory 2.4 3.1 Other current assets 1.0 0.4 Property, plant and equipment, net 449.4 464.8 Equity method investments 250.0 253.7 Operating lease right-of-use assets 20.9 24.2 Goodwill 12.2 12.2 Intangible assets, net 153.9 160.1 Other non-current assets 25.6 12.1 Total assets $ 935.1 $ 956.4 LIABILITIES AND DEFICIT Accounts payable $ 8.2 $ 6.7 Accounts payable to related parties 64.4 — Current portion of operating lease liabilities 6.8 8.7 Accrued expenses and other current liabilities 17.4 12.9 Long-term debt 899.0 992.3 Asset retirement obligations 6.5 6.0 Operating lease liabilities, net of current portion 14.1 15.4 Other non-current liabilities 22.7 22.7 Deficit (104.0) (108.3) Total liabilities and deficit $ 935.1 $ 956.4 Effective May 1, 2020, Delek through its wholly owned subsidiaries Lion Oil Company (“Lion Oil”) and Delek Refining, Ltd. (“Delek Refining”) contributed certain leased and owned tractors and trailers and related assets used in the provision of trucking and transportation services for crude oil, petroleum and certain other products throughout Arkansas, Oklahoma and Texas to Delek Trucking, LLC (“Delek Trucking”), a direct wholly owned subsidiary of Lion Oil. Following this contribution, Lion Oil sold all of the issued and outstanding membership interests in Delek Trucking (the “Trucking Acquisition”) to DKL Transportation, LLC (“DKL Transportation”), a wholly owned subsidiary of Delek Logistics. Promptly following the consummation of the Trucking Acquisition, Delek Trucking merged with and into DKL Transportation, with DKL Transportation continuing as the surviving entity. Total consideration for the Trucking Acquisition was approximately $48.0 million in cash, subject to certain post-closing adjustments, financed primarily with borrowings under Delek Logistics’ revolving credit facility. In connection with the Trucking Acquisition, Delek Refining, Lion Oil and DKL Transportation entered into a Transportation Services Agreement pursuant to which DKL Transportation will gather, coordinate the pickup of, transport and deliver petroleum products for Delek Refining and Lion Oil, as well as provide ancillary services as requested. Prior periods have not been recast in our Note 3 - Segment Data, as these assets did not constitute a business in accordance with ASU 2017-01, Clarifying the Definition of a Business ("ASU 2017-01" ) , and the transaction was accounted for as an acquisition of assets between entities under common control. Effective March 31, 2020, Delek Logistics, through its wholly-owned subsidiary DKL Permian Gathering, LLC, acquired the Permian Gathering System (previously referred to as the Big Spring Gathering System), located in Howard, Borden and Martin Counties, Texas, from Delek, which included the execution of related commercial agreements. In connection with the closing of the transaction, Delek, Delek Logistics and various of their respective subsidiaries entered into a Throughput and Deficiency Agreement (the “T&D Agreement”). Under the T&D Agreement, Delek Logistics will operate and maintain the Permian Gathering System connecting our interests in and to certain crude oil production with the Delek Logistics' Big Spring, Texas terminal and provide gathering, transportation and other related services. The total consideration was subject to certain post-closing adjustments and was comprised of $100.0 million in cash and 5.0 million common units representing limited partner interest in Delek Logistics. The cash component of this dropdown was financed with borrowings on the DKL Credit Facility (as defined in Note 10). Prior periods have not been recast in our Note 3 - Segment Data, as these assets did not constitute a business in accordance with ASU 2017-01 and the transaction was accounted for as an acquisition of assets between entities under common control.

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments	Equity Method Investments Wink to Webster Pipeline On July 30, 2019, we, through our wholly-owned direct subsidiary Delek Energy, entered into a limited liability company agreement (the “LLCA”) and related agreements with multiple joint venture members of Wink to Webster Pipeline LLC (“WWP”). Pursuant to the LLCA, Delek Energy acquired a 15% ownership interest in WWP ("WWP Joint Venture"). WWP intends to construct and operate a crude oil pipeline system from Wink, Texas to Webster, Texas along with certain pipelines from Webster, Texas to other destinations in the Gulf Coast area. Pursuant to the LLCA, Delek Energy will be required to contribute its percentage interest of the applicable construction costs (including certain costs previously incurred by WWP). Construction of the majority of the pipeline system is complete, with initial operation commencing in October 2020 and full commercial operation under the Transportation Service Agreements commencing in February 2022. During the year ended December 31, 2020, we made capital contributions totaling $18.9 million. On February 21, 2020, we through our wholly-owned direct subsidiary Delek Energy, entered into the W2W Holdings LLC Agreement with MPLX Operations LLC ("MPLX") (collectively, with its wholly-owned subsidiaries, the "WWP Project Financing Joint Venture" or the "WWP Project Financing JV"). The WWP Project Financing JV was created for the specific purpose of obtaining financing to fund our combined capital calls resulting from and occurring during the construction period of the pipeline system under the WWP Joint Venture, and to service that debt. In connection with the arrangement, both Delek Energy and MPLX contributed their respective 15% ownership interests to the WWP Project Financing JV as collateral for and in service of the related project financing. Accordingly, distributions received from WWP through the WWP Project Financing JV will first be applied in service of the related project financing debt, with excess distributions being made to the members of the WWP Project Financing JV as provided for in the W2W Holdings LLC Agreement and as allowed under the project financing debt. The obligations of the members under the joint venture are guaranteed by the parents of the members of the WWP Project Financing JV. The Company evaluated Delek's investment in W2W Holdings LLC ("HoldCo") and determined that HoldCo is a VIE. The Company determined it is not the primary beneficiary since it does not have the power to direct activities that most significantly impact HoldCo. The Company does not hold a controlling financial interest in HoldCo because no single party has the power to direct the activities that most significantly impact HoldCo’s economic performance since power to make the decisions about the significant activities is shared equally with MPLX and all significant decisions require unanimous consent of the board of directors of HoldCo. The Company accounts for its investment in HoldCo using the equity method of accounting due to its significant influence with its 50% membership interest. The Company's maximum exposure to any losses incurred by HoldCo is limited to its investment. As of December 31, 2021, except for the guarantee of member obligations under the joint venture, the Company does not have other existing guarantees with or to HoldCo, or any third-party for work contracted with it. On September 30, 2021 WWP made the decision to buy Delek out of the Midland Connector Financing Commitment Agreement which provided an interest-free commitment to fund us up to $65.0 million upon completion of a connector to connect the WWP long-haul pipeline to our Permian Gathering System, with repayment over 14 years. The buy-out totaled $27.5 million and represented the estimated incremental cost of capital to fund the $65.0 million in expenditures over a 14-year term, and enabled us to recover approximately $18.0 million of capital expenditures that we may not have incurred had it not been for the financing commitment, including approximately $6.6 million that was written off. As a result of the transaction, for the year ended December 31, 2021 we recognized $20.9 million of other non-operating income, representing the excess over recognized write-offs. As of December 31, 2021 and 2020, Delek's investment balance in WWP Project Financing Joint Venture totaled $49.3 million and $66.6 million, respectively, and is included as part of total assets in corporate, other and eliminations in our segment disclosure. During the year ended December 31, 2020, we received distributions of $69.3 million from WWP Project Financing Joint Venture to return excess capital contributions made. In addition to the investment, we recognized a loss of $17.7 million and $8.5 million for the years ended December 31, 2021 and 2020, respectively. Delek Logistics Investments In May 2019, Delek Logistics, through its wholly owned indirect subsidiary DKL Pipeline, LLC (“DKL Pipeline”), entered into a Contribution and Subscription Agreement (the “Contribution Agreement”) with Plains Pipeline, L.P. (“Plains”) and Red River Pipeline Company LLC (“Red River”). Pursuant to the Contribution Agreement, DKL Pipeline contributed $124.7 million, substantially all of which was financed under the Delek Logistics Credit Facility (as defined in Note 10), to Red River in exchange for a 33% membership interest in Red River and DKL Pipeline’s admission as a member of Red River ("Red River Pipeline Joint Venture"). Red River owns a 16-inch crude oil pipeline running from Cushing, Oklahoma to Longview, Texas. In August 2020, Red River completed a planned expansion project to increase the pipeline capacity which commenced operations on October 1, 2020. Delek Logistics contributed an additional $3.5 million related to such expansion project in May 2019 and during 2020 made additional capital contributions totaling $12.2 million based on capital calls received. As of December 31, 2021 and 2020, Delek's investment balance in Red River totaled $144.0 million and $141.8 million, respectively. We recognized income on the investment totaling $14.5 million and $8.9 million for the years ended December 31, 2021 and 2020, respectively. This investment is accounted for using the equity method and is included as part of total assets in our logistics segment. In addition to Red River, Delek Logistics has two other joint ventures that own and operate logistics assets, and which serve third parties and subsidiaries of Delek. We own a 50% membership interest in the entity formed with an affiliate of Plains All American Pipeline, L.P. to operate one of these pipeline systems (the "Caddo Pipeline") and a 33% membership interest in Andeavor Logistics Rio Pipeline LLC which operates the other pipeline system (the "Rio Pipeline"). As of December 31, 2021 and 2020, Delek Logistics' investment balance in these joint ventures was $106.0 million and $111.9 million, respectively, and are accounted for using the equity method. We recognized income on these investments totaling $10.1 million and $13.8 million for the years ended December 31, 2021 and 2020, respectively. Other Investments We have a 50% interest in a joint venture that owns an asphalt terminal located in Brownwood, Texas. As of December 31, 2021 and 2020, Delek's investment balance in the Brownwood, Texas joint venture was $41.6 million and $39.3 million, respectively. We recognized income on this investment totaling $10.7 million and $15.4 million for the years ended December 31, 2021 and 2020, respectively. This investment is accounted for using the equity method and is included as part of total assets in the corporate, other and eliminations in our segment disclosure. Delek Renewables, LLC, a wholly-owned subsidiary of Delek, has a 50% interest in a joint venture that owns, operates and maintains a terminal consisting of an ethanol unit train facility with an ethanol tank in North Little Rock, Arkansas. As of December 31, 2021 and 2020, Delek Renewables, LLC's investment balance in this joint venture was $3.2 million and $4.0 million, respectively, and was accounted for using the equity method. We recognized nominal income on this investment for the both years ended December 31, 2021 and 2020. The investment in this joint venture is reflected in the refining segment.

Discontinued Operations and Disposal Groups [Abstract]
Discounted Operations	Discontinued Operations California Discontinued Entities During the third quarter 2017, we committed to a plan to sell certain assets associated with our Paramount and Long Beach, California refineries (both non-operating refineries) and our California renewable fuels facility ("AltAir"), which were acquired as part of the Delek/Alon Merger ("California Discontinued Entities"). Such operations were designated and reported as discontinued operations. Sale of Paramount Refinery Assets and Altair On March 16, 2018, Delek sold to World Energy, LLC ("World Energy") (i) all of Delek’s membership interests in AltAir (ii) certain refining assets and other related assets located in Paramount, California and (iii) certain associated tank farm and pipeline assets and other related assets located in California. The sale involved initial proceeds due at closing, a subsequent working capital settlement as well as contingent proceeds for Delek's pro rata portion of any BTC relating to AltAir activities in 2018 earned through the sale date in connection with the re-enactment of the 2018 BTC that occurred in December 2019, and other final adjustments on retained contingent liabilities. The loss from discontinued operations was subsequently reduced in 2019 by $8.1 million. Also, an additional loss of $3.4 million was recognized in discontinued operations related to the sale of the Paramount assets in 2019. Sale of Long Beach Refinery Net Assets The transaction to dispose of certain assets and liabilities associated with our Long Beach, California refinery to Bridge Point Long Beach, LLC closed July 17, 2018. We retained certain asset retirement obligations in connection with the disposition of the Long Beach refinery related to work that was required subsequent to the sale. As of December 31, 2019, the work was completed and the remaining unused asset retirement obligations were written off resulting in an additional gain on sale of discontinued operations of $1.9 million. Operating Results of Discontinued Operations The operating results, net of tax, from discontinued operations associated with the California Discontinued Entities are presented separately in Delek’s consolidated statements of income and the notes to the consolidated financial statements have been adjusted to exclude the discontinued operations. Classification as discontinued operations requires retrospective reclassification of the associated assets, liabilities and results of operations for all periods presented. The loss from discontinued operations was subsequently reduced in 2019 by $6.6 million.

At December 31, 2020, we recorded a pre-tax inventory valuation reserve of $31.1 million, $30.3 million of which related to LIFO inventory, which reversed in the first quarter of 2021 due to the sale of inventory quantities that gave rise to the December 31, 2020 reserve. For the years ended December 31, 2021, 2020 and 2019, we recognized a net reduction (increase) in cost of materials and other in the accompanying consolidated statements of income related to the change in pre-tax inventory valuation of $22.3 million, $(29.2) million and $52.3 million, respectively. At December 31, 2021 and 2020, the excess of replacement cost compared to the carrying value (LIFO) of the Tyler refinery inventories was $68.4 million and $3.4 million, respectively.

Inventory Supply and Offtake Obligations	Inventory Supply and Offtake Obligations Delek has Supply and Offtake Agreements with J. Aron in connection with its El Dorado, Big Spring and Krotz Springs refineries. Pursuant to the Supply and Offtake Agreements, (i) J. Aron agrees to sell to us, and we agree to buy from J. Aron, at market prices, crude oil for processing at these refineries and (ii) we agree to sell, and J. Aron agrees to buy, at market prices, certain refined products produced at these refineries. The Supply and Offtake Agreements also provide for the lease to J. Aron of crude oil and refined product storage facilities, and the identification of prospective purchasers of refined products on J. Aron’s behalf. At the inception of the Supply and Offtake Agreements, we transferred title to a certain number of barrels of crude and other inventories to J. Aron (the "Step-In"), and the Supply and Offtake Agreements require the repurchase of remaining inventory (including certain "Baseline Volumes") at the termination of those Agreements (the "Step-Out"). The Supply and Offtake Agreements are accounted for as inventory financing arrangements under the fair value election provided by ASC 815 and ASC 825. Barrels subject to the Supply and Offtake Agreements are as follows (in millions): El Dorado Big Spring Krotz Springs Baseline Volumes pursuant to the respective Supply and Offtake Agreements 2.0 0.8 1.3 Barrels of inventory consigned under the respective Supply and Offtake Agreements as of December 31, 2021 (1) 3.5 1.3 1.2 Barrels of inventory consigned under the respective Supply and Offtake Agreements as of December 31, 2020 (1) 4.0 1.3 1.2 (1) Includes Baseline Volumes plus/minus over/short quantities. The Supply and Offtake Agreements have certain termination provisions, which may include requirements to negotiate with third parties for the assignment to us of certain contracts, commitments and arrangements, including procurement contracts, commitments for the sale of product, and pipeline, terminalling, storage and shipping arrangements. The Supply and Offtake Agreements were amended in December 2018 for Big Spring and in January 2019 for El Dorado and Krotz Springs so that the repurchase of Baseline Volumes at the end of the Supply and Offtake Agreement term (representing the "Baseline Step-Out Liability" or, collectively, the "Baseline Step-Out Liabilities") were based upon a fixed price where, prior to those amendments, the Baseline Step-Out Liabilities were based on market-indexed pricing. As a result of these amendments, the subsequent changes in fair value of the Baseline Step-Out Liabilities were recorded in interest expense. In September 2019, we amended the Supply and Offtake Agreements to increase the fixed Step-Out price on Baseline Volumes. As a result of the change in the contractual terms, we received cash, net of estimated fees paid, totaling approximately $38.9 million. No gain or loss was recognized as a result of these September 2019 amendments. In January 2020, we amended our three Supply and Offtake Agreements so that the Baseline Step-Out Liabilities were once again based on market-indexed prices subject to commodity price risk. As a result of the amendment, such Baseline Step-Out Liabilities continued to be recorded at fair value under the fair value election provided by ASC 815 and ASC 825, where the fair value now reflected changes in commodity price risk rather than interest rate risk with subsequent changes in fair value being recorded in cost of materials and other. In April 2020, we amended and restated our three Supply and Offtake Agreements to renew and extend the terms to December 30, 2022, with J. Aron having the sole discretion to further extend to May 30, 2025 by giving at least 6 months prior notice to the current maturity date. As part of this amendment, there were changes to the underlying market index, annual fee, the crude purchase fee, crude roll fees and timing of cash settlements related to periodic price adjustments (the "Periodic Price Adjustments"). The Baseline Step-Out Liabilities continue to be recorded at fair value under the fair value election included under ASC 815 and ASC 825. The Baseline Step-Out Liabilities have a floating component whose fair value reflects changes to commodity price risk with changes in fair value recorded in cost of materials and other and a fixed component whose fair value reflects changes to interest rate risk with changes in fair value recorded in interest expense. There was no amendment date change in fair value resulting from the modification. The Baseline Step-Out Liabilities are reflected as non-current liabilities on our consolidated balance sheet to the extent that they are not contractually due within twelve months. Monthly activity resulting in over and short volumes are be valued using market-indexed pricing, and are included in current liabilities (or receivables) on our consolidated balance sheet. Pursuant to the Periodic Price Adjustments provision in the Supply and Offtake Agreements, the Company may be required to pay down all or a portion of the fixed component of the Baseline Step-Out Liabilities or may receive additional proceeds depending on the change in fair value of the inventory collateral subject to a threshold at certain specified Periodic Pricing Dates, which occur on October 1st and May 1st, annually, not to extend beyond expiration of the Supply and Offtake Agreements. Additionally, at the Periodic Pricing Dates, if a Periodic Price Adjustment is triggered, the prospective pricing underlying the fixed component of the Baseline Step-Out Liabilities will be adjusted to reflect either the pay-down or the incremental proceeds, accordingly. On October 1, 2020, the provision was triggered and a paydown amounting to $20.8 million was made to J. Aron on October 30, 2020. The prospective pricing underlying the fixed component of the Baseline Step-Out liabilities was adjusted accordingly to reflect this payment, resulting in a reduction to the fixed differential component of our long-term Supply and Offtake Obligation totaling $20.8 million and a prospective contractual reset of the fixed differentials subject to future Periodic Price Adjustments. Contemporaneous with the payment, J. Aron separately refunded to us the $10.0 million of deferred additional monthly fees. On May 1, 2021 the provision was triggered and on May 28, 2021, $15.2 million of incremental proceeds were received from J. Aron. Effective June 4, 2021, J. Aron terminated our $10.0 million letter of credit that was issued to them under the terms of the Supply and Offtake Agreements. As of December 31, 2021, the fixed component of the Baseline Step-Out Liabilities subject to the Periodic Price Adjustments amounted to approximately $38.6 million. All or some portion of that amount may become due or payable if Periodic Price Adjustments are triggered in May 2021 and October 2021. Gains (losses) related to changes in fair value due to commodity-index price are recorded as a component of cost of materials and other, and changes in fair value due to interest rate risk are recorded as a component of interest expense in the consolidated statements of income. With respect to the Baseline Step-Out liabilities, we recognized gains (losses) in cost of materials and other attributable to changes in fair value due to commodity-index price totalin g $105.5 million, and $(51.5) million for the y ears ended December 31, 2021 and 2020. Before the January 2020 amendments, the fair value of the fixed price Baseline Step-Out liabilities were based on changes to interest rates reflecting changes to the interest rate risk, and such effect is included in total interest expense for that period, as disclosed below.

(4) Net of deferred financing costs of $5.7 million at December 31, 2021. Delek Revolver and Term Loan On March 30, 2018 (the "Closing Date"), Delek entered into (i) a new term loan credit agreement with Wells Fargo Bank, National Association, as administrative agent (the "Term Administrative Agent"), Delek, as borrower, certain subsidiaries of Delek, as guarantors, and the lenders from time to time party thereto, providing for a senior secured term loan facility in an amount of $700.0 million (the "Term Loan Credit Facility") and (ii) a second amended and restated credit agreement with Wells Fargo Bank, National Association, as administrative agent (the "Revolver Administrative Agent"), Delek, as borrower, certain subsidiaries of Delek, as guarantors, and the other lenders party thereto, providing for a senior secured asset-based revolving credit facility with commitments of $1.0 billion (the "Revolving Credit Facility" and, together with the Term Loan Credit Facility, the "New Credit Facilities"). The Revolving Credit Facility permits borrowings in Canadian dollars of up to $50.0 million. The Revolving Credit Facility also permits the issuance of letters of credit of up to $400.0 million, including letters of credit denominated in Canadian dollars of up to $10.0 million. Delek may designate restricted subsidiaries as additional borrowers under the Revolving Credit Facility. The Term Loan Credit Facility was drawn in full for $700.0 million on the Closing Date at an original issue discount of 0.50%. Proceeds under the Term Loan Credit Facility, as well as proceeds of approximately $300.0 million in borrowings under the Revolving Credit Facility on the Closing Date, were used to repay certain indebtedness of Delek and its subsidiaries (the “Refinancing”), as well as certain fees, costs and expenses in connection with the closing of the New Credit Facilities with any remaining proceeds held in cash. Proceeds of future borrowings under the Revolving Credit Facility will be used for working capital and general corporate purposes of Delek and its subsidiaries. On May 22, 2019 (the "First Incremental Effective Date"), we amended the Term Loan Credit Facility agreement pursuant to the terms of the First Incremental Amendment to Term Loan Credit Agreement (the "Incremental Amendment"). Pursuant to the Incremental Amendment, the Company borrowed $250.0 million in aggregate principal amount of incremental term loans (the “Incremental Term Loans”) at an original issue discount of 0.75%. On November 12, 2019 (the "Second Incremental Effective Date"), we amended the Term Loan Credit facility agreement pursuant to the terms of the Second Incremental Amendment to the Term Loan Credit Agreement (the "Second Incremental Amendment") and borrowed $150.0 million in aggregate principal amount of incremental term loans (the "Incremental Loans") at an original issue discount of 1.21%, increasing the aggregate principal amount of loans outstanding under the Term Loan Credit Facility on the Second Incremental Effective Date to $1,088.3 million. The terms of the Incremental Term Loans and Incremental Loans are substantially identical to the terms applicable to the initial term loans under the Term Loan Credit Facility borrowed in March 2018. There are no restrictions on the Company's use of the proceeds of the Incremental Term Loans and Incremental Loans. The proceeds may be used for (i) reducing utilizations under the Revolving Credit Facility, (ii) general corporate purposes and (iii) paying transaction fees and expenses associated with the incremental amendments. On May 19, 2020, we amended the Term Loan Credit Facility agreement and borrowed $200.0 million in aggregate principal amount of incremental term loans (the “Third Incremental Term Loan”) at an original issue discount of 7.00%. The Third Incremental Term Loan constitutes a separate class of term loan (the "Class B Loan") under the Term Loan Credit Facility from those initially borrowed in March 2018 and the incremental term loans borrowed in May 2019 and November 2019 (collectively, the "Class A Loans"). Delek may voluntarily prepay the outstanding Third Incremental Term Loan at any time subject to customary breakage costs with respect to LIBOR loans and subject to a prepayment premium of 1.00% in connection with certain customary repricing events that may occur during the period from the day after the first anniversary of the Third Incremental Term Loan through the second anniversary of the Third Incremental Term Loan. The other terms of the Third Incremental Term Loan are substantially identical to the terms applicable to the Class A Loans. The proceeds of the Third Incremental Term Loan may be used (i) for general corporate purposes and (ii) to pay transaction fees and expenses associated with the Third Incremental Term Loan. Interest and Unused Line Fees The interest rates applicable to borrowings under the Term Loan Credit Facility and the Revolving Credit Facility are based on a fluctuating rate of interest measured by reference to either, at Delek’s option, (i) a base rate, plus an applicable margin, or (ii) a reserve-adjusted LIBOR, plus an applicable margin (or, in the case of Revolving Credit Facility borrowings denominated in Canadian dollars, the Canadian dollar bankers' acceptances rate ("CDOR")). On October 26, 2018, Delek entered into an amendment to the Term Loan Credit Facility (the “First Amendment”) to reduce the margin on certain borrowings under the Term Loan Credit Facility and incorporate certain other changes. The First Amendment decreased the applicable margins for Class A Loans under (i) Base Rate Loans by 0.25% to 1.25% and (ii) LIBOR Rate Loans by 0.25% to 2.25%, as such terms are defined in the Term Loan Credit Facility. Class B Loans incurred under the Third Incremental Term Loan bear interest at a rate that is determined, at the Company’s election, at LIBOR or at base rate, in each case, plus an applicable margin of 5.50% with respect to LIBOR borrowings and 4.50% with respect to base rate borrowings. Additionally, Class B loans that are LIBOR borrowings are subject to a minimum LIBOR rate floor of 1.00%. The applicable margin for Revolving Credit Facility borrowings is based on Delek’s excess availability as determined by reference to a borrowing base, ranging from 0.25% to 0.75% per annum with respect to base rate borrowings and from 1.25% to 1.75% per annum with respect to LIBOR and CDOR borrowings. In addition, the Revolving Credit Facility requires Delek to pay an unused line fee on the average amount of unused commitments thereunder in each quarter, which fee will be at a rate of 0.25% or 0.375% per annum, depending on average commitment usage for such quarter. As of December 31, 2021, the unused line fee was set at 0.375% per annum. Maturity and Repayments The Revolving Credit Facility will mature and the commitments thereunder will terminate on March 30, 2023. The Term Loan Credit Facility matures on March 30, 2025 and requires scheduled quarterly principal payments on the last business day of the applicable quarter. Pursuant to the Incremental Amendment, quarterly payments increased from $1.75 million to $2.38 million. Pursuant to the Second Incremental Amendment, the quarterly payments increased to $2.75 million commencing with December 31, 2019. Additionally, the Term Loan Credit Facility requires prepayments by Delek with the net cash proceeds from certain debt incurrences, asset dispositions and insurance or condemnation events with respect to Delek’s assets, subject to certain exceptions, thresholds and reinvestment rights. The Term Loan Credit Facility also requires annual prepayments with a variable percentage of Delek’s excess cash flow, ranging from 50% to 0% depending on Delek’s consolidated fiscal year end secured net leverage ratio. The Third Incremental Term Loan requires quarterly payments on the Class B Loans of $0.5 million commencing June 30, 2020. Guarantee and Security The obligations of the borrowers under the New Credit Facilities are guaranteed by Delek and each of its direct and indirect, existing and future, wholly-owned domestic subsidiaries, subject to customary exceptions and limitations, and excluding Delek Logistics, Delek Logistics GP, LLC, and each subsidiary of the foregoing (collectively, the "MLP Subsidiaries"). Borrowings under the New Credit Facilities are also guaranteed by DK Canada Energy ULC, a British Columbia unlimited liability company and a wholly-owned restricted subsidiary of Delek. The Revolving Credit Facility is secured by a first priority lien over substantially all of Delek’s and each guarantor's receivables, inventory, RINs, instruments, intercompany loan receivables, deposit and securities accounts and related books and records and certain other personal property, subject to certain customary exceptions (the "Revolving Priority Collateral"), and a second priority lien over substantially all of Delek's and each guarantor's other assets, including all of the equity interests of any subsidiary held by Delek or any guarantor (other than equity interests in certain MLP Subsidiaries) subject to certain customary exceptions, but excluding real property (such real property and equity interests, the "Term Priority Collateral"). The Term Loan Credit Facility is secured by a first priority lien on the Term Priority Collateral and a second priority lien on the Revolving Priority Collateral, all in accordance with an intercreditor agreement between the Term Administrative Agent and the Revolver Administrative Agent and acknowledged by Delek and the subsidiary guarantors. Certain excluded assets are not included in the Term Priority Collateral and the Revolving Priority Collateral. Additional Information At December 31, 2021, the weighted average borrowing rate under the Revolving Credit Facility was 3.50% and there were no principal amounts outstanding thereunder. Additionally, there were letters of credit issued of approximately $270.4 million as of December 31, 2021 under the Revolving Credit Facility. Unused credit commitments under the Revolving Credit Facility, as of December 31, 2021, were approximately $729.6 million. At December 31, 2021, the weighted average borrowing rate under the Term Loan Credit Facility was approximately 3.00% comprised entirely of LIBOR borrowings and the principal amount outstanding thereunder was $1,260.0 million. As of December 31, 2021, the effective interest rate related to the Term Loan Credit Facility was 3.53%. Delek Hapoalim Term Loan On December 31, 2019, Delek entered into an unsecured term loan credit and guaranty agreement (the "Agreement") with Bank Hapoalim B.M. ("BHI") as the administrative agent. Pursuant to the Agreement, on December 31, 2019, Delek borrowed $40.0 million (the "BHI Term Loan"). The interest rate under the Agreement is equal to LIBOR plus a margin of 3.00%. The Agreement has a maturity date of December 31, 2022 and requires quarterly loan amortization payments of $0.1 million, commencing March 31, 2020. Proceeds may be used for general corporate purposes. On December 30, 2020 and June 28, 2021, we amended the BHI Term Loan to modify one of the required quarterly financial covenant metrics; there were no other changes as a result of this amendment. At December 31, 2021, the weighted average borrowing rate under the term loan was approximately 3.10% comprised entirely of a LIBOR borrowing and the principal amount outstanding thereunder was $29.2 million. On July 30, 2021, we elected to voluntarily prepay $10.0 million in principal of the term loan. As of December 31, 2021, the effective interest rate related to the BHI Term Loan was 3.67%. Delek Logistics Credit Facility On September 28, 2018, Delek Logistics and all of its subsidiaries entered into a third amended and restated senior secured revolving credit agreement with Fifth Third Bank ("Fifth Third") as administrative agent and a syndicate of lenders (hereafter, the "Delek Logistics Credit Facility") with lender commitments of $850.0 million. The Delek Logistics Credit Facility also contains an accordion feature whereby Delek Logistics can increase the size of the credit facility to an aggregate of $1.0 billion, subject to receiving increased or new commitments from lenders and the satisfaction of certain other conditions precedent. The obligations under the Delek Logistics Credit Facility remain secured by first priority liens on substantially all of Delek Logistics' tangible and intangible assets. The Delek Logistics Credit Facility has a maturity date of September 28, 2023. Borrowings under the Delek Logistics Credit Facility bear interest at either a U.S. dollar prime rate, Canadian dollar prime rate, LIBOR, or a CDOR rate, in each case plus applicable margins, at the election of the borrowers and as a function of draw down currency. The applicable margin, in each case, and the fee payable for the unused revolving commitments vary based upon Delek Logistics' most recent total leverage ratio calculation delivered to the lenders, as called for and defined under the terms of the Delek Logistics Credit Facility. At December 31, 2021, the weighted average borrowing rate was approximately 2.46%. Additionally, the Delek Logistics Credit Facility requires Delek Logistics to pay a leverage ratio dependent quarterly fee on the average unused revolving commitment. As of December 31, 2021, this fee was 0.30% on an annualized basis. In connection with the elimination of IDRs in August 2020, Delek Logistics entered into a First Amendment to the Delek Logistics Credit Facility which, among other things, permitted the transfer of cash and equity consideration for the elimination of IDRs. It also modified the total leverage ratio and the senior leverage ratio (each as defined in the Delek Logistics Credit Facility) calculations to reduce the total funded debt (as defined in the Delek Logistics Credit Facility) component thereof by the total amount of unrestricted consolidated cash and cash equivalents on the balance sheet of Delek Logistics and its subsidiaries up to $20.0 million. As of December 31, 2021, Delek Logistics had $258.0 million of outstanding borrowings under the Delek Logistics Credit Facility, with no letters of credit in place. Unused credit commitments under the Delek Logistics Credit Facility as of December 31, 2021, were $592.0 million.

(“Finance Corp.” and together with Delek Logistics, the “Issuers”) issued $250.0 million in aggregate principal amount of 6.75% senior notes due in 2025 (the “Delek Logistics 2025 Notes”) at a discount. The Delek Logistics 2025 Notes are general unsecured senior obligations of the Issuers.

The Delek Logistics 2028 Notes will mature on June 1, 2028, and interest is payable semi-annually in arrears on each June 1 and December 1, commencing December 1, 2021. At any time prior to June 1, 2024, the Co-issuers may redeem up to 35% of the aggregate principal amount of the Delek Logistics 2028 Notes with the net cash proceeds of one or more equity offerings by Delek Logistics at a redemption price of 107.125% of the redeemed principal amount, plus accrued and unpaid interest, if any, subject to certain conditions and limitations.

In addition, beginning on June 1, 2024, the Co-issuers may, subject to certain conditions and limitations, redeem all or part of the Delek Logistics 2028 Notes, at a redemption price of 103.563% of the redeemed principal for the twelve-month period beginning on June 1, 2024, 101.781% for the twelve-month period beginning on June 1, 2025, and 100.00% beginning on June 1, 2026 and thereafter, plus accrued and unpaid interest, if any. In the event of a change of control, accompanied or followed by a ratings downgrade within a certain period of time, subject to certain conditions and limitations, the Co-issuers will be obligated to make an offer for the purchase of the Delek Logistics 2028 Notes from holders at a price equal to 101.00% of the principal amount thereof, plus accrued and unpaid interest. As of December 31, 2021, we had $400.0 million in outstanding principal amount under the Delek Logistics 2028 Notes, and the effective interest rate was 7.41%. Reliant Bank Revolver Delek has an unsecured revolving credit agreement with Reliant Bank (the "Reliant Bank Revolver"). On December 16, 2019, we amended the Reliant Bank Revolver to extend the maturity date to June 30, 2022, reduce the fixed interest rate from 4.75% to 4.50% per annum and increase the revolver commitment amount from $30.0 million to $50.0 million. There were no other significant changes to the agreement in connection with this amendment. On December 9, 2020 and June 17, 2021, we amended the Reliant Bank Revolver to modify one of the required quarterly financial covenant metrics; there were no other changes as a result of this amendment. The revolving credit agreement requires us to pay a quarterly fee of 0.50% per year on the average unused revolving commitment. As of December 31, 2021, we had $50.0 million outstanding under this facility and had no unused credit commitments under the Reliant Bank Revolver. Promissory Notes Delek had four unsecured notes payable (the "Promissory Notes") for a total of $120.0 million in principal with various assignees of Alon Israel Oil Company, Ltd., the holder of a predecessor consolidated promissory note, which bore interest at a fixed rate of 5.50% per annum and which, collectively, required annual principal amortization payments of $25.0 million, with a final principal amortization payment of $20.0 million which was paid at maturity of the Promissory Notes on January 4, 2021. Restrictive Covenants Under the terms of our Revolving Credit Facility, Term Loan Credit Facility, Delek Logistics Credit Facility, Delek Logistics 2025 Notes, Delek Logistics 2028 Notes, Reliant Bank Revolver and BHI Agreement, we are required to comply with certain usual and customary financial and non-financial covenants. The terms and conditions of the Revolving Credit Facility include periodic compliance with a springing minimum fixed charge coverage ratio financial covenant if excess availability under the revolver borrowing base is below certain thresholds, as defined in the credit agreement. The Term Loan Credit Facility does not have any financial maintenance covenants. We believe we were in compliance with all covenant requirements under each of our credit facilities as of December 31, 2021. Certain of our debt facilities contain limitations on the incurrence of additional indebtedness, making of investments, creation of liens, dispositions and acquisitions of assets, and making of restricted payments and transactions with affiliates. These covenants may also limit the payment, in the form of cash or other assets, of dividends or other distributions, or the repurchase of shares with respect to our equity. Additionally, certain of our debt facilities limit our ability to make investments, including extensions of loans or advances to, or acquisitions of equity interests in, or guarantees of obligations of, any other entities. Restricted Net Assets Some of Delek's subsidiaries have restrictions in their respective credit facilities limiting their use of assets, as has been discussed above. As of December 31, 2021, we had no subsidiaries with restricted net assets which would prohibit earnings from being transferred to the parent company for its use.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments We use the majority of our derivatives to reduce normal operating and market risks with the primary objective of reducing the impact of market price volatility on our results of operations. As such, our use of derivative contracts is aimed at: • limiting our exposure to commodity price fluctuations on inventory above or below target levels (where appropriate) within each of our segments; • managing our exposure to commodity price risk associated with the purchase or sale of crude oil, feedstocks/intermediates and finished grade fuel within each of our segments; • managing our exposure to market crack spread fluctuations; • managing the cost of our RINs Obligation using future commitments to purchase or sell RINs at fixed prices and quantities; and • limiting the exposure to interest rate fluctuations on our floating rate bo rrowings. We primarily utilize commodity swaps, futures, forward contracts and options contracts, generally with maturity dates of three years or less, and from time to time interest rate swaps or caps to achieve these objectives. Futures contracts are standardized agreements, traded on a futures exchange, to buy or sell the commodity at a predetermined price and location at a specified future date. Options provide the right, but not the obligation to buy or sell a commodity at a specified price in the future. Commodity swaps and futures contracts require cash settlement for the commodity based on the difference between a fixed or floating price and the market price on the settlement date, and options require payment/receipt of an upfront premium. Because these derivatives are entered into to achieve objectives specifically related to our inventory and production risks, such gains and losses (to the extent not designated as accounting hedges and recognized on an unrealized basis in other comprehensive income) are recognized in cost of materials and other. Forward contracts are agreements to buy or sell a commodity at a predetermined price at a specified future date, and for our transactions, generally require physical delivery. Forward contracts where the underlying commodity will be used or sold in the normal course of business qualify as NPNS pursuant to ASC 815. If we elect the NPNS exception, such forward contracts are not accounted for as derivative instruments but rather are accounted for under other applicable GAAP. Commodity forward contracts accounted for as derivative instruments are recorded at fair value with changes in fair value recognized in earnings in the period of change. Our Canadian crude trading operations are accounted for as derivative instruments, and the related unrealized and realized gains and losses are recognized in other operating income, net on the accompanying consolidated statements of income. Additionally, as of and for the year ended December 31, 2021, other forward contracts accounted for as derivatives that are specific to managing crude costs rather than for trading purposes are recognized in cost of materials and other on the consolidated statements of income in our refining segment, and are included in our disclosures of commodity derivatives in the tables below. Futures, swaps or other commodity related derivative instruments that are utilized to specifically provide economic hedges on our Canadian forward contract or investment positions are recognized in other operating income, net because that is where the related underlying transactions are reflected. From time to time, we also enter into future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our RINs Obligation. These future RINs commitment contracts meet the definition of derivative instruments under ASC 815, and are recorded at estimated fair value in accordance with the provisions of ASC 815. Changes in the fair value of these future RINs commitment contracts are recorded in cost of materials and other on the consolidated statements of income. At this time, we do not believe there is any material credit risk with respect to the counterparties to any of our derivative contracts. In accordance with ASC 815, certain of our commodity swap contracts have been designated as cash flow hedges and the change in fair value between the execution date and the end of period has been recorded in other comprehensive income. The fair value of these contracts is recognized in income in the same financial statement line item as hedged transaction at the time the positions are closed and the hedged transactions are recognized in income. The following table presents the fair value of our derivative instruments as of December 31, 2021 and 2020. The fair value amounts below are presented on a gross basis and do not reflect the netting of asset and liability positions permitted under our master netting arrangements, including cash collateral on deposit with our counterparties. We have elected to offset the recognized fair value amounts for multiple derivative instruments executed with the same counterparty in our financial statements. As a result, the asset and liability amounts below differ from the amounts presented in our consolidated balance sheets.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Our assets and liabilities that are measured at fair value include commodity derivatives, investment commodities, environmental credits obligations and Supply and Offtake Agreements. ASC 820 requires disclosures that categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants. Our commodity derivative contracts, which consist of commodity swaps, exchange-traded futures, options and physical commodity forward purchase and sale contracts (that do not qualify for the NPNS exception under ASC 815), are valued based on exchange pricing and/or price index developers such as Platts or Argus and are, therefore, classified as Level 2. In April 2020, we entered into a contract with the Department of Energy to deposit one million barrels of crude oil into one of the Strategic Petroleum Reserve ("SPR") storage locations which was stored on our behalf until October 2020 for a fee of approximately 100,000 barrels. The fee of 100,000 barrels was recorded as a prepaid asset at cost, and the right to receive the 900,000 barrels was recorded as a financial asset, measured at fair value based on the value of the underlying commodity using published market prices of the commodity on the applicable exchange. Such asset was, therefore, classified as Level 2. Such barrels were received in the fourth quarter of 2020. The realized gain on the underlying commodity related to the SPR financial asset for the year ended December 31, 2020 of $10.8 million was recorded in other (income) expense, net. Our RINs commitment contracts are future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our Consolidated Net RINs Obligation. These RINs commitment contracts (which are forward contracts accounted for as derivatives – see Note 12) are categorized as Level 2, and are measured at fair value based on quoted prices from an independent pricing service. Our environmental credits obligation surplus or deficit includes the Consolidated Net RINs Obligation surplus or deficit, as well as other environmental credit obligation surplus or deficit positions subject to fair value accounting pursuant to our accounting policy (see Note 2). The environmental credits obligation surplus or deficit is categorized as Level 2, if measured at fair value either directly through observable inputs or indirectly through market-corroborated inputs, and gains (losses) related to changes in fair value are recorded as a component of cost of materials and other in the consolidated statements of income. With respect to our Consolidated Net RINs Obligation surplus or deficit, we recognized gains (losses) on changes in fair value totaling $17.8 million and $(15.2) million for the years ended December 31, 2020 and 2019, respectively, primarily attributable to changes in the market prices of the underlying credits that occurred at the end of each quarter. For the year ended December 31, 2021, we recognized gains (losses) on changes in fair value totaling $(44.5) million, which was attributable to changes in estimated volume requirements related to the 2021 RINs Obligation to reflect the December 2021 Proposed EPA Rule (where a rule regarding 2021 requirements had not been previously enacted) as well as to quarterly changes in the market prices of the underlying credits. The environmental credits obligation is impacted by government regulation requiring such credits, and the obligation, and likewise the value of the underlying credits, may be impacted by exemptions granted by the regulatory agencies. During the third quarter of 2019, the Tyler, El Dorado and Krotz Springs refineries received approval from the EPA for a small refinery exemption from the requirements of the renewable fuel standard ("RIN Waivers") for the 2018 calendar year, which resulted in a reduction of our Consolidated Net RINs Obligation and related cost of materials and other of approximately $20.7 million for the year ended December 31, 2019. During the first quarter 2019, the Tyler and Big Spring refineries received RIN Waivers for the 2017 calendar year, which had an immaterial impact on our results of operations. We have not received any additional RIN Waivers impacting the years ended December 31, 2021 and 2020. As of and for the years ended December 31, 2021 and 2020, we elected to account for our J. Aron step-out liability at fair value in accordance with ASC 825, as it pertains to the fair value option. This standard permits the election to carry financial instruments and certain other items similar to financial instruments at fair value on the balance sheet, with all changes in fair value reported in earnings. With respect to the amended and restated Supply and Offtake Agreements, such amendments being effective April 2020 for all the agreements, we apply fair value measurement as follows: (1) we determine fair value for our amended variable step-out liability based on changes in fair value related to market volatility based on a floating commodity-index price, and for our amended fixed step-out liability based on changes to interest rates and the timing and amount of expected future cash settlements where such obligation is categorized as Level 2. Gains (losses) related to changes in fair value due to commodity-index price are recorded as a component of cost of materials and other, and changes in fair value due to interest rate risk are recorded as a component of interest expense in the consolidated statements of income; and (2) we determine fair value of the commodity-indexed revolving over/short inventory financing liability based on the market prices for the consigned crude oil and refined products collateralizing the financing/funding where such obligation is categorized as Level 2 and is presented in the current portion of the Obligation under Supply and Offtake Agreements on our consolidated balance sheets. Before the January 2020 amendments, we determined the fair value for the fixed price step-out liability based on changes to interest rates reflecting changes to the interest rate risk, with obligation categorized as Level 2. See Note 9 for discussion of gains and losses recognized from changes in fair value. For all other financial instruments, the fair value approximates the historical or amortized cost basis comprising our carrying value and therefore are not included in the table below. The fair value hierarchy for our financial assets and liabilities accounted for at fair value on a recurring basis was as follows (in millions): As of December 31, 2021 Level 1 Level 2 Level 3 Total Assets Commodity derivatives $ — $ 129.1 $ — $ 129.1 RINs commitment contracts — 1.6 — 1.6 Total assets — 130.7 — 130.7 Liabilities Commodity derivatives — (108.4) — (108.4) RINs commitment contracts — (0.7) — (0.7) Environmental credits obligation deficit — (172.2) — (172.2) J.

In the table above, derivative assets and liabilities with the same counterparty are not netted where the legal right of offset exists. This differs from the presentation in the financial statements which reflects our policy, wherein we have elected to offset the fair value amounts recognized for multiple derivative instruments executed with the same counterparty and where the legal right of offset exists. As of December 31, 2021 and 2020, $(24.7) million and $14.8 million, respectively, of cash (obligation) collateral was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty. See Note 11 for further information regarding derivative instruments.

Commitments and Contingencies

Commitments and Contingencies	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation In the ordinary conduct of our business, we are from time to time subject to lawsuits, investigations and claims, including environmental claims and employee-related matters. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, including civil penalties or other enforcement actions, we do not believe that any currently pending legal proceeding or proceedings to which we are a party will have a material adverse effect on our financial statements. Certain environmental matters that have or may result in penalties or assessments are discussed below in the "Environmental, Health and Safety" section of this note. One of our Alon subsidiaries was the defendant in a legal action related to an easement dispute arising from a purchase of property that occurred in October 2013, prior to the Delek/Alon Merger. In June 2019, the court found in favor of the plaintiffs and assessed damages against such subsidiary totaling $6.7 million, which was reduced to $6.4 million in the fourth quarter of 2019. Such amount is included as of December 31, 2021 and December 31, 2020 in accrued expenses and other current liabilities on the accompanying consolidated balance sheet. As a result of this liability, a $5.7 million increase in the accrual was recorded during the year ended December 31, 2019. The matter was appealed, and has been remanded to the district court regarding jurisdictional issues. On June 19, 2017, the Arkansas Teacher Retirement System filed a lawsuit in the Delaware Court of Chancery (Arkansas Teacher Retirement System v. Alon USA Energy, Inc., et al., Case No. 2017-0453), asserting claims for breach of fiduciary duty in connection with the business combination of Delek US Holdings, Inc. and Alon USA Energy, Inc. Following a mediation, the parties to the litigation agreed to a settlement and release of all claims of the plaintiff class in exchange for the defendants' agreement to pay $44.8 million into a settlement fund, of which our insurance carriers agreed to fund approximately $42.5 million under the applicable insurance policies and pursuant to varying limits and limitations. The settlement, in which the Company and other defendants expressly deny all assertions of wrongdoing or fault, was approved by the Court on October 29, 2021. In addition to the $2.3 million of the settlement that was not covered by insurance, we accrued $4.2 million of estimated unpaid and remaining legal fees. As of December 31, 2021, the remaining unpaid balance is $0.7 million, and is included in accrued expenses and other current liabilities on the accompanying consolidated balance sheet. Self-insurance Delek records a self-insurance accrual for workers’ compensation claims up to a $4.0 million deductible on a per accident basis, general liability claims up to $4.0 million on a per occurrence basis, and medical claims for eligible full-time employees up to $0.3 million per covered individual per calendar year. We also record a self-insurance accrual for auto liability up to a $4.0 million deductible on a per accident basis. We have umbrella liability insurance available to each of our segments in an amount determined reasonable by management. Environmental, Health and Safety We are subject to extensive federal, state and local environmental and safety laws and regulations enforced by various agencies, including the EPA, the United States Department of Transportation and the Occupational Safety and Health Administration ("OSHA"), as well as numerous state, regional and local environmental, safety and pipeline agencies. These laws and regulations govern the discharge of materials into the environment, waste management practices, pollution prevention measures and the composition of the fuels we produce, as well as the safe operation of our plants and pipelines and the safety of our workers and the public. Numerous permits or other authorizations are required under these laws and regulations for the operation of our refineries, renewable fuels facilities, terminals, pipelines, underground storage tanks, trucks, rail cars and related operations, and may be subject to revocation, modification and renewal. These laws and permits raise potential exposure to future claims and lawsuits involving environmental and safety matters which could include soil and water contamination, air pollution, personal injury and property damage allegedly caused by substances which we manufactured, handled, used, released or disposed of, transported, or that relate to pre-existing conditions for which we have assumed responsibility. We believe that our current operations are in substantial compliance with existing environmental and safety requirements. However, there have been and will continue to be ongoing discussions about environmental and safety matters between us and federal and state authorities, including notices of violations, citations and other enforcement actions, some of which have resulted or may result in changes to operating procedures and in capital expenditures. While it is often difficult to quantify future environmental or safety related expenditures, we anticipate that continuing capital investments and changes in operating procedures will be required for the foreseeable future to comply with existing and new requirements, as well as evolving interpretations and more strict enforcement of existing laws and regulations. As of December 31, 2021, we have recorded an environmental liability of approximately $112.2 million, primarily related to the estimated probable costs of remediating or otherwise addressing certain environmental issues of a non-capital nature at our refineries, as well as terminals, some of which we no longer own. This liability includes estimated costs for ongoing investigation and remediation efforts for known contamination of soil and groundwater. Approximately $2.7 million of the total liability is expected to be expended over the next 12 months, with most of the balance expended by 2032, although some costs may extend up to 30 years. In the future, we could be required to extend the expected remediation period or undertake additional investigations of our refineries, pipelines and terminal facilities, which could result in the recognition of additional remediation liabilities. Included in our environmental liabilities as of both December 31, 2021 and 2020 is a liability totaling $78.5 million related to a property that we have historically operated as an asphalt and marine fuel terminal both as an owner and, subsequently, as a lessee under an in-substance lease agreement (the “License Agreement”). The License Agreement, which provided us the license to continue operating our asphalt and marine fuel terminal operations on the property for a term of ten years (expiring in June 2020), also ascribed a contractual noncontingent indemnification guarantee to certain of our wholly-owned subsidiaries related to certain incremental environmental remediation activities, predicated on the completion of certain property development activities ascribed to the lessor. Our combined liability, comprised of our environmental liability plus the estimated fair value of the noncontingent guarantee liability, was recorded in connection with the Delek/Alon Merger, effective July 1, 2017. While the License Agreement expired in June 2020, it is currently being disputed in litigation where we have determined that no loss accrual is necessary and that the amount of incremental loss that is reasonably possible is immaterial as of December 31, 2021. Such ongoing dispute causes sufficient uncertainty around the release of risk and the appropriate joint and several liability allocations thereunder that we cannot currently determine a more reasonable estimate of the potential total contingent liability that is probable, nor do we have sufficient information to better estimate the fair value of any remaining noncontingent guarantee liability. As such, as of December 31, 2021 and 2020, except for accretion and expenditures, our combined environmental liability related to the terminal and property remained unchanged. Environmental liabilities with payments that are fixed or reliably determinable have been discounted to present value at various rates depending on their expected payment stream. These discount rates vary from 1.51% to 2.84%. The table below summaries our environmental liability accruals (in millions): December 31, 2021 2020 Discounted environmental liabilities $ 34.4 $ 35.3 Undiscounted environmental liabilities 77.8 77.3 Total accrued environmental liabilities $ 112.2 $ 112.6 As of December 31, 2021, the estimated future payments of environmental obligations for which discounts have been applied are as follows (in millions): 2022 $ 1.9 2023 1.5 2024 1.5 2025 1.5 2026 1.6 Thereafter 30.4 Discounted environmental liabilities, gross 38.4 Less: Discount applied 4.0 Discounted environmental liabilities $ 34.4 We are also subject to various regulatory requirements related to carbon emissions and the compliance requirements to remit environmental credit obligations due to the EPA or other regulatory agencies, the most significant of which relates to the RINs Obligation subject to the EPA’s RFS-2 regulations (See Note 2 for further discussion). The RFS-2 regulations are highly complex and evolving, requiring us to periodically update our compliance systems. As part of our on-going monitoring and compliance efforts, on an annual basis we engage a third party to perform procedures to review our RINs inventory, processes and compliance. The results of such procedures may include procedural findings but may also include findings regarding the usage of RINs to meet past obligations, the treatment of exported RINs, and the propriety of RINs on-hand and related adjustments to our RINs inventory, which (to the extent they are valued) offset our RINs Obligation. Such adjustments may also require communication with the EPA if they involve reportable non-compliance which could lead to the assessment of penalties. Based on management’s review which was completed during the second quarter 2021, we recorded a RINs inventory true-up adjustment totaling $(12.3) million which increased our recorded RINs Obligation. We have also self-reported our related instances of non-compliance to the EPA, and while we cannot yet estimate the extent of penalties that may be assessed, it is not expected to be material in relation to our total RINs Obligation. Other Losses and Contingencies Delek maintains property damage insurance policies which have varying deductibles. Delek also maintains business interruption insurance policies, with varying coverage limits and waiting periods. Covered losses in excess of the deductible and outside of the waiting period will be recoverable under th e property and business interruption insurance policies. El Dorado Refinery Fire On February 27, 2021, our El Dorado refinery experienced a fire in its Penex unit. Six employees were injured in the fire, which was investigated by OSHA. Contrary to initial assessments, and despite occurring during the early stages of turnaround activity, the facility did suffer operational disruptions as a result of the fire. During the year ended December 31, 2021, we incurred workers' compensation losses of $3.8 million and accrued an additional $4.0 million for uncovered litigation, claims and assessments associated with the fire, which are included in operating expenses in the consolidated statements of income. Additionally, we recognized accelerated depreciation of $1.0 million due to property damaged in the fire, which was recovered during the year ended December 31, 2021. An additional $7.4 million was recognized as a gain, in excess of these losses, during the year ended December 31, 2021. We continue to incur repair costs that may be recoverable under property and casualty insurance policies. In addition, during the year ended December 31, 2021, we recognized a gain of $8.8 million related to business interruption claims. Such gain is included in other operating income in the consolidated statements of income. If applicable, we accrue receivables for probable insurance or other third-party recoveries. Work to determine the full extent of covered business interruption and property and casualty losses and potential insurance claims is ongoing and may result in the future recognition of insurance recoveries. Winter Storm Uri During February 2021, the Company experienced a severe weather event ("Winter Storm Uri") which temporarily impacted operations at all of our refineries. Due to the extreme freezing conditions, we experienced reduced throughputs at our refineries as there was a disruption in the crude supply, as well as damages to various units at our refineries requiring additional operating and capital expenditures. We recognized additional operating expenses in the amount of $17.5 million during the year ended December 31, 2021 due to property damaged in the freeze which was recovered during the year ended December 31, 2021. An additional $5.0 million was recognized as a gain, in excess of these losses during the year ended December 31, 2021. We continue to incur additional repair costs that may be recoverable under property and casualty insurance policies. We also recognized a gain of $1.1 million related to business interruption claims. Such gain is included in other operating income in the consolidated statements of income. If applicable, we accrue receivables for probable insurance or other third-party recoveries. Work to determine the full extent of covered business interruption and property and casualty losses and potential insurance claims is ongoing and may result in additional future recognition of insurance recoveries. Crude Oil and Other Releases We have experienced several crude oil and other releases involving our assets, including five releases that occurred in 2019. There were no material releases that occurred during the years ended December 31, 2021 and 2020. For releases that occurred in prior years, we have received regulatory closure or a majority of the cleanup and remediation efforts are substantially complete.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. On March 27, 2020, the CARES Act was enacted into law. The CARES Act includes several significant provisions for corporations, including the usage of net operating losses, interest deductions and payroll benefits. The Company recognized $16.8 million of current federal income tax benefit for the year ended December 31, 2020, attributable to anticipated tax refunds from net operating loss carryback to prior 35% tax rate years under the CARES Act. Also, we recorded a federal income tax receivable specifically related to the net operating loss carryback totaling $156.2 million; a current receivable of $135.6 million and a non-current receivable of $20.6 million. The full amount of this tax receivable was received during the third quarter of 2021. Significant components of Delek's deferred tax assets (liabilities) reported in the accompanying consolidated financial statements as of December 31, 2021 and 2020 were as follows (in millions): December 31, 2021 2020 Non-Current Deferred Taxes: Property, plant and equipment, and intangibles $ (270.6) $ (261.0) Right-of-use asset (44.6) (35.1) Derivatives and hedging (9.3) 0.3 Partnership and equity investments (142.5) (133.3) Deferred revenues (6.3) (4.8) Total deferred tax liabilities (473.3) (433.9) Interest expense limitation under 163j 18.9 0.3 Compensation and employee benefits 12.6 13.6 Net operating loss carryforwards 181.2 136.4 Tax credit carryforwards 17.5 17.0 Lease obligation 44.4 35.2 Reserves and accruals 37.9 33.4 Inventories 28.1 2.7 Other 0.4 0.8 Total deferred tax assets 341.0 239.4 Valuation allowance (59.0) (55.0) Total net deferred tax liabilities (1) $ (191.3) $ (249.5) (1) Total net deferred tax liabilities includes $5.1 million and $6.0 million of state deferred tax assets recorded in other non-current assets in our consolidated balance sheet.at December 31, 2021 and December 31, 2020, respectively., The difference between the actual income tax expense and the tax expense computed by applying the statutory federal income tax rate to income from continuing operations was attributable to the following (in millions): Year Ended December 31, 2021 2020 2019 Provision for federal income taxes at statutory rate $ (48.9) $ (160.3) $ 84.6 State income tax (benefit) expense, net of federal tax provision (1.9) (11.3) 6.3 Income tax benefit attributable to non-controlling interest (7.1) (7.9) (5.4) Tax credits and incentives (1) (8.6) (9.6) (23.2) Changes in valuation allowance 4.0 (10.8) 7.3 Impact of CARES Act net operating loss carryback — (16.8) — Goodwill impairment — 21.4 — Other items — 2.6 2.1 Income tax (benefit) expense $ (62.5) $ (192.7) $ 71.7 (1) Tax credits and incentives include work opportunity and research and development credits, as well as incentives for the Company’s biodiesel blending operations. Income tax (benefit) expense from continuing operations was as follows (in millions): Year Ended December 31, 2021 2020 2019 Current $ (3.1) $ (160.6) $ 7.1 Deferred (59.4) (32.1) 64.6 $ (62.5) $ (192.7) $ 71.7 We carry valuation allowances against certain state deferred tax assets and net operating losses that may not be recoverable with future taxable income. We also carry valuation allowances related to basis differences that may not be recoverable. During the years ended December 31, 2021 and 2020, we recorded an increase to the valuation allowance of $4.0 million and a decrease of $10.8 million, respectively. The 2021 increase in the valuation allowance was primarily driven by changes in the state tax attributes, whereas in 2020 the decrease was driven by the reversal of allowance for deferred tax asset in partnership investments due to changes in the future realizability of deferred tax basis differences. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods for which the deferred tax assets are deductible, management believes it is more likely than not Delek will realize the benefits of these deductible differences, net of the existing valuation allowance. The amount of the deferred tax assets considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced. Subsequently recognized tax benefit or expense relating to the valuation allowance for deferred tax assets will be reported as an income tax benefit or expense in the consolidated statement of income. Federal net operating loss and credit carryforwards at December 31, 2021 totaled $549.9 million and $16.4 million, respectively, a portion of which are subject to a valuation allowance. Federal net operating losses have an indefinite carryforward life, and federal tax credit carryforwards will begin expiring in 2028. State net operating loss and credit carryforwards at December 31, 2021 totaled $1,460.5 million and $1.3 million, respectively, a portion of which are subject to a valuation allowance. State net operating losses and tax credit carryforwards will begin expiring in 2022. Delek files a consolidated U.S. federal income tax return, as well as income tax returns in various state jurisdictions. Delek is no longer subject to U.S. federal income tax examinations by tax authorities for years through 2011. Delek is under Joint Committee of Taxation review for tax years 2012 through 2020. Pre-acquisition tax returns for Alon are closed for U.S. federal income tax examinations through the tax year ended December 31, 2016 as of December 31, 2021. Alon is currently under Joint Committee of Taxation review for tax year 2017. Alon USA Partners, LP is currently under audit by the IRS for tax year 2019. Delek is currently under audit in various states for tax years 2016 through 2019. No material adjustments have been identified at this time. ASC 740 provides a recognition threshold and guidance for measurement of income tax positions taken or expected to be taken on a tax return. ASC 740 requires the elimination of the income tax benefits associated with any income tax position where it is not "more likely than not" that the position would be sustained upon examination by the taxing authorities. Increases and decreases to unrecognized tax benefits, which includes immaterial interest and penalties, were as follows (in millions): Year Ended December 31, 2021 2020 2019 Balance at the beginning of the year $ 9.6 $ 12.1 $ 19.2 Additions based on tax positions related to current year 4.2 1.9 0.4 Additions for tax positions related to prior years and acquisitions 1.7 2.4 6.4 Reductions for tax positions related to prior years (0.3) (0.8) (13.0) Reductions for tax positions related to lapse of applicable statute of limitations (1.1) (0.2) — Settlements with taxing authorities — (5.8) (0.9) Balance at the end of the year $ 14.1 $ 9.6 $ 12.1 The amount of the unrecognized benefit above, that if recognized would change the effective tax rate, is $6.5 million and $6.2 million as of December 31, 2021 and 2020, respectively. Delek recognizes accrued interest and penalties related to unrecognized tax benefits as an adjustment to the current provision for income taxes. We recognized interest expense (income) of $0.3 million, $0.5 million, and $(1.1) million related to unrecognized tax benefits during the years ended December 31, 2021, 2020 and 2019. The total recognized liability for interest was $1.5 million and $1.4 million as of December 31, 2021 and 2020, respectively. Uncertain tax positions have been examined by Delek for any material changes in the next 12 months, and no material changes are expected.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill Goodwill represents the excess of the aggregate purchase price over the fair value of the identifiable net assets acquired and is not amortized. Delek performs an annual assessment of whether goodwill retains its value. This assessment is done more frequently if indicators of potential impairment exist. We performed our annual goodwill impairment review in the fourth quarter of 2021, 2020 and 2019. This review was performed at the reporting unit level, which is at or one level below our operating segment. We estimated the value of each of our reporting units using a discounted cash flows ("DCF") analysis and a multiple of expected future cash flows, such as those used by third-party analysts. The DCF analysis included a market participant weighted average cost of capital, forecasted crack spreads, gross margin, capital expenditures, and long-term growth rate based on historical information and our best estimate of future forecasts. The market approach involves significant judgment, including selection of an appropriate peer group, selection of valuation multiples, and determination of the appropriate weighting in our valuation model. With respect to the goodwill associated with the reporting units within the logistics segment, we performed a qualitative assessment in 2021, 2020 and 2019. For the year ended December 31, 2020, the annual impairment review resulted in an impairment charge of $126.0 million. For the years ended December 31, 2021 and 2019, no impairment of goodwill occurred. Accumulated goodwill impairment was $126.0 million as of December 31, 2021. A summary of our goodwill by segment is as follows (in millions): Refining Logistics Retail Corporate, Other and Eliminations Total Balance, December 31, 2018 $ 801.3 $ 12.2 $ 44.3 $ — $ 857.8 Write-off of goodwill associated with retail stores sold — — (2.1) — (2.1) Balance, December 31, 2019 801.3 12.2 42.2 — 855.7 Goodwill Impairment (126.0) — — — (126.0) Balance, December 31, 2020 675.3 12.2 42.2 — 729.7 Goodwill Impairment — — — — — Balance, December 31, 2021 $ 675.3 $ 12.2 $ 42.2 $ — $ 729.7 .

Equity-Based Compensation	Equity-Based Compensation Delek US Holdings, Inc. 2006 Long-Term Incentive Plan The Delek US Holdings, Inc. 2006 Long-Term Incentive Plan, as amended (the "2006 Plan"), allowed Delek to grant stock options, stock appreciation rights ("SARs"), RSUs, PRSUs, and other stock-based awards of up to 5,053,392 shares of Delek's common stock to certain directors, officers, employees, consultants and other individuals who performed services for Delek or its affiliates. Stock options and SARs granted under the 2006 Plan were generally granted at market price or higher. The vesting of all outstanding awards was subject to continued service to Delek or its affiliates except that vesting of awards granted to certain executive employees could, under certain circumstances, accelerate upon termination of their employment and the vesting of all outstanding awards could accelerate upon the occurrence of an Exchange Transaction (as defined in the 2006 Plan). In the second quarter of 2010, Delek's Board of Directors and its Incentive Plan Committee began using stock-settled SARs, rather than stock options, as the primary form of appreciation award under the 2006 Plan. The 2006 Plan expired in April 2016. Delek US Holdings, Inc. 2016 Long-Term Incentive Plan On May 5, 2016, our stockholders approved our 2016 Long-Term Incentive Plan (the “2016 Plan”) to succeed our 2006 Plan. The 2016 Plan allows Delek to grant stock options, SARs, restricted stock, RSUs, performance awards and other stock-based awards of up to 4,400,000 shares of Delek's common stock to certain directors, officers, employees, consultants and other individuals who perform services for Delek or its affiliates. On May 18, 2018, May 5, 2020 and May 6 2021, the Company's stockholders approved an amendment to the 2016 plan that increased the number of shares of common stock available under this plan by 4,500,000 shares, 2,120,000 shares and 3,215,000 shares, respectively, to 14,235,000 shares. Stock options and SARs issued under the 2016 Plan are granted at prices equal to (or greater than) the fair market value of Delek's common stock on the grant date and are generally subject to a vesting period of one year or more. No awards will be made under the 2016 Plan after May 5, 2026. Alon USA Energy, Inc. 2005 Long-Term Incentive Plan In connection with the Delek/Alon Merger, Delek assumed the Alon USA Energy, Inc. Second Amended and Restated 2005 Incentive Compensation Plan (“the Alon 2005 Plan” and, collectively with the 2006 Plan and the 2016 Plan, the "Incentive Plans") as a component of its overall executive incentive compensation program. The Alon 2005 Plan permits the granting of awards to Alon's officers and key employees in the form of options to purchase common stock, SARs, restricted shares of common stock, RSUs, performance shares, performance units and senior executive plan bonuses. Effective with the Delek/Alon Merger, all contractually unvested share-based awards were converted into share-based awards denominated in Delek common stock. Committed but unissued share-based awards were exchanged and converted into rights to receive share-based awards indexed to Delek common stock. The Alon 2005 Plan was terminated June 4, 2021. Option and SAR Assumptions The table below provides the fair value assumptions for our outstanding stock options and SARs under the Incentive Plans. For all awards granted, we calculated volatility using historical and implied volatility of a peer group of public companies using weekly stock prices. 2019 Grants (Grade Vesting - 4 years) Expected volatility 48.16%-48.94% Dividend yield 2.03%-2.60% Expected term 4.57- 4.62 years Risk free rate 1.57%-2.41% Fair value per share $11.46 Stock Option and SAR Activity The following table summarizes our Incentive Plans stock option and SAR activity for the years ended December 31, 2021, 2020 and 2019: Number of Shares Under Option Weighted-Average Strike Price Weighted-Average Contractual Term (in years) Average Intrinsic Value Options and SARs outstanding, December 31, 2018 3,574,105 $ 32.67 Granted 593,500 $ 34.96 Exercised (466,569) $ 29.61 Forfeited (494,826) $ 33.47 Options and SARs outstanding, December 31, 2019 3,206,210 $ 34.21 Granted 17,000 $ 36.56 Exercised (23,675) $ 14.68 Forfeited (709,055) $ 34.25 Options and SARs outstanding, December 31, 2020 2,490,480 $ 34.16 Granted — $ — Exercised (28,025) $ 15.67 Forfeited (389,225) $ 38.10 Options and SARs outstanding, December 31, 2021 2,073,230 $ 33.79 5.8 nominal Vested options and SARs exercisable, December 31, 2021 1,758,730 $ 32.62 5.6 nominal Restricted Stock Units The Incentive Plans provide for the award of RSUs and PRSUs to certain employees and non-employee directors.

These amounts are included in general and administrative expenses and operating expenses in the accompanying consolidated statements of income. We recognized income tax expense (benefits) for equity-based awards of $1.7 million, $2.3 million and $(2.5) million for the years ended December 31, 2021, 2020 and 2019, respectively. As of December 31, 2021, there was $33.0 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements, which is expected to be recognized over a weighted-average period of 1.3 years. The aggregate intrinsic value, which represents the difference between the underlying stock's market price and the award's exercise price, of the share-based awards exercised or vested during the years ended December 31, 2021, 2020 and 2019 was $13.0 million, $8.4 million and $27.0 million, respectively. During the years December 31, 2021, 2020 and 2019, respectively, we issued net shares of common stock of 415,212, 369,843 and 508,950 as a result of exercised or vested equity-based awards. These amounts are net of 196,451, 167,094 and 564,090 shares, respectively, withheld to satisfy employee tax obligations related to the exercises and vesting for the years ended December 31, 2021, 2020 and 2019. Delek paid approximately $4.2 million, $2.4 million and $9.2 million of taxes in connection with the settlement of these awards for the years ended December 31, 2021, 2020 and 2019. We issue new shares of common stock upon exercise or vesting of share-based awards. Delek Logistics GP, LLC 2012 Long-Term Incentive Plan Logistics GP maintains a unit-based compensation plan for officers, directors and employees of Logistics GP or its affiliates and certain consultants, affiliates of Logistics GP or other individuals who perform services for Delek Logistics. The Delek Logistics GP, LLC 2012 Long-Term Incentive Plan ("Logistics LTIP") permits the grant of unit options, restricted units, phantom units, unit appreciation rights, distribution equivalent rights, other unit-based awards, and unit awards. Awards granted under the Logistics LTIP will be settled with Delek Logistics units. On June 9, 2021, the Logistics GP board of directors amended the Logistics LTIP and increased the number of common units representing limited partner interests in Delek Logistics (the "Common Units") authorized for issuance under this plan by 300,000 Common Units to 912,207 Common Units. The term of the Logistics LTIP was also extended to June 9, 2031. Equity-based compensation expense is included in general and administrative expenses in the accompanying consolidated statements of income and is immaterial for the years ended December 31, 2021, 2020 and 2019. Delek US Holdings, Inc. Employee Stock Purchase Plan On June 2, 2021, the Company's board of directors adopted the Delek US Holdings, Inc. Employee Stock Purchase Plan (the "ESPP"). The ESPP is structured as a qualified employee stock purchase plan under Section 423 of the U.S. Internal Revenue Code of 1986. The Company authorized the issuance of 2,000,000 shares of common stock under the ESPP. On each purchase date, eligible employees (as defined in the ESPP) can purchase the Company's stock at a price per share equal to 85.0% of the closing price of the Company's common stock on the exercise date, but no less than par value. There are four offering periods of three months during each fiscal year, beginning each January 1st, April 1st, July 1st, and October 1st. No shares of common stock were issued under the ESPP during the year ended December 31, 2021. Implementation of the plan will be effective in 2022.

Stockholder Rights Plan On March 20, 2020, our Board of Directors declared a dividend of one preferred share purchase right (a “Right”) for each outstanding share of Delek’s common stock and adopted a stockholder rights plan (the “Rights Agreement”). The dividend was distributed in a non-cash transaction on March 30, 2020 to the stockholders of record on that date. The Rights initially traded with Delek’s common stock and expired in accordance with the terms of the Rights Agreement on March 19, 2021. Preferred Stock On March 20, 2020, our Board of Directors authorized 1,000,000 shares of preferred stock with a par value of $0.01 per share as Series A Junior Participating Preferred Stock. Stock Repurchase Program On November 6, 2018, our Board of Directors authorized a share repurchase program for up to $500.0 million of Delek common stock. Any share repurchases under the repurchase program may be implemented through open market transactions or in privately negotiated transactions, in accordance with applicable securities laws. The timing, price and size of repurchases will be made at the discretion of management and will depend on prevailing market prices, general economic and market conditions and other considerations. The repurchase program does not obligate us to acquire any particular amount of stock and does not expire. During the year ended December 31, 2020 and 2019, we repurchased 58,713 and 5,039,034 shares of our common stock for a total of $1.9 million and $178.1 million, respectively. No repurchases of our common stock were made in the year ended December 31, 2021. As of December 31, 2021, there was approximately $229.7 million of authorization remaining under Delek's aggregate stock repurchase program (based on repurchases that had settled as of December 31, 2021). During the year ended December 31, 2020, we suspended the share repurchase program until our internal parameters are met for resuming such repurchases.

Retirement Benefits [Abstract]
Employees	Employees Workforce As of December 31, 2021, operations, maintenance and warehouse hourly employees along with truck drivers at the Tyler refinery were represented by the United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union and its Local 202. Of the Tyler refinery employees, 55.9% of operations, maintenance and warehouse hourly employees are currently covered by a collective bargaining agreement that expires January 31, 2028 while 8.5% of Tyler refinery truck drivers are currently covered by a collective bargaining agreement that expires October 31, 2024. As of December 31, 2021, operations, maintenance and warehouse hourly employees at the El Dorado refinery were represented by the International Union of Operating Engineers and its Local 351. Of the El Dorado refinery employees, 40.4% are covered by a collective bargaining agreement which expires on August 1, 2027. As of December 31, 2021, approximately 68.3% of employees who work at our Big Spring refinery were covered by a collective bargaining agreement that expires March 31, 2027. None of our employees in our logistics segment, retail segment or in our corporate office are represented by a union. We consider our relations with our employees to be satisfactory. Postretirement Benefits Pension Plans Effective with the Delek/Alon Merger, we had four defined benefit pension plans covering substantially all of Alon's employees, excluding employees of the retail segment. The benefits are based on years of service and the employee’s final average monthly compensation. Our funding policy is to contribute annually no less than the minimum required nor more than the maximum amount that can be deducted for federal income tax purposes. Contributions are intended to provide not only for benefits attributed to service to date but also for those benefits expected to be earned in the future. The plans were frozen for non-union employees effective September 30, 2017. During 2018, we completely settled the supplemental retirement income plan of the retail segment, had a partial settlement of Alon's executive non-qualified restoration plan, froze Alon's qualified pension plan for union employees effective July 31, 2018, and entered into an agreement with the International Union of Operating Engineers (the "Union") to extend the Union agreement to March 31, 2022. As part of the extended Union agreement, the Company agreed to compensate each pension-eligible employee in the Union for the loss of the pension benefit over the remaining union contract period in four annual installments beginning July 2018. Payments are contingent upon continued employment at each annual payment date and are expected to total approximately $6.9 million in the aggregate without considering forfeitures (which cannot yet be estimated). The related expense (estimated without considering forfeitures) has been or will be recognized over the remaining union contract period. As of December 31, 2021, estimated remaining expense is approximately $0.1 million during 2022. On October 1, 2018, we spun off a portion of the Alon's qualified pension plan into a new plan - The Alon USA Pension Plan for Collectively Bargained Employees. This new plan consists of Union employees. The assets were allocated as required under IRC Section 414. The remaining accumulated other comprehensive income at that date was split between the two plans based on their respective portions of projected benefit obligation. The Alon USA Pension Plan for Collectively Bargained Employees was terminated. The plan's obligation was settled and paid out from the plan's asset on December 20, 2019. The pre-tax amounts related to the defined benefit plans recognized as pension benefit liability in the consolidated balance sheets as of December 31, 2021 was $2.9 million. Financial information related to our pension plans is presented below (in millions): Year Ended December 31, 2021 2020 Change in projected benefit obligation: Benefit obligation at beginning of year $ 148.7 $ 131.5 Interest cost 3.5 4.2 Actuarial loss (gain) (5.5) 18.3 Benefits paid (5.6) (5.3) Other (effect of curtailment/settlement) (0.3) — Projected benefit obligations at end of year $ 140.8 $ 148.7 Change in plan assets: Fair value of plan assets at beginning of year $ 138.5 $ 128.1 Actual gain on plan assets 5.0 15.7 Employer contribution 0.3 — Benefits paid (5.6) (5.3) Other (effect of curtailment/settlement) (0.3) — Fair value of plan assets at end of year $ 137.9 $ 138.5 Reconciliation of funded status: Fair value of plan assets at end of year $ 137.9 $ 138.5 Less projected benefit obligations at end of year 140.8 148.7 Under-funded status at end of year $ (2.9) $ (10.2) The pre-tax amounts in accumulated other comprehensive income (loss) that have not yet been recognized as components of net periodic benefit cost were as follows (in millions): Year Ended December 31, 2021 2020 Net actuarial loss $ 4.9 $ 9.3 Prior service credit — — Projected benefit obligations at end of year $ 4.9 $ 9.3 The accumulated benefit obligation for each of our pension plans was in excess of the fair value of plan assets. The projected benefit obligation, accumulated benefit obligation and fair value of plan assets for the pension plans were as follows (in millions): Year Ended December 31, 2021 2020 Projected benefit obligation $ 140.8 $ 148.7 Accumulated benefit obligation $ 140.8 148.7 Fair value of plan assets $ 137.9 138.5 The weighted-average assumptions used to determine benefit obligations were as follows: Year Ended December 31, 2021 2020 Discount rate 2.75 % 2.45 % The discount rate used reflects the expected future cash flow based on our funding valuation assumptions and participant data as of the beginning of the plan period. The expected future cash flow is discounted by the Principal Pension Discount Yield Curve for the fiscal year end because it has been specifically designed to help pension funds comply with statutory funding guidelines. The expected long-term rate of return is based on the portfolio as a whole and not on the sum of the returns on individual asset categories. The weighted-average assumptions used to determine net periodic benefit costs were as follows: Year Ended December 31, 2021 2020 2019 Discount rate 2.45 % 3.20 % 4.15 % Expected long-term rate of return on plan assets 4.65 % 5.75 % 7.00 % The components of net periodic benefit cost related to our benefit plans consisted of the following (in millions): Year Ended December 31, Components of net periodic benefit: 2021 2020 2019 Interest cost 3.5 4.2 5.4 Expected return on plan assets (6.0) (6.8) (7.5) Recognition of gain due to curtailment — — (2.7) Net periodic benefit $ (2.5) $ (2.6) $ (4.8) The service cost component of net periodic benefit is included as part of general and administrative expenses in the accompanying statements of income. The other components of net periodic benefit are included as part of other non-operating expense (income), net. The weighted-average asset allocation of our pension benefits plan assets were as follows: Year Ended December 31, 2021 2020 Investments in common collective trust consisting of: U.S. and International companies 21.2 % 40.4 % Fixed-income 78.8 % 59.6 % Total 100.0 % 100.0 % The fair value of our pension assets by category were as follows (in millions): Quoted Prices in Active Markets For Identical Assets or Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Consolidated Year Ended December 31, 2021 U.S. companies $ — $ 19.3 $ — $ 19.3 International companies — 9.9 — 9.9 Fixed-income — 108.7 — 108.7 Total $ — $ 137.9 $ — $ 137.9 Year Ended December 31, 2020 U.S. companies $ — $ 36.2 $ — $ 36.2 International companies — 19.7 — 19.7 Fixed-income — 82.6 — 82.6 Total $ — $ 138.5 $ — $ 138.5 The investment policies and strategies for the assets of our pension benefits is to, over a five-year period, provide returns in excess of the benchmark. The portfolio in our common collective trust is expected to earn long-term returns from capital appreciation and a stable stream of current income. This approach recognizes that assets are exposed to price risk and the market value of the plans’ assets may fluctuate from year to year. Risk tolerance is determined based on our specific risk management policies. In line with the investment return objective and risk parameters, the plans’ mix of assets includes a diversified portfolio of underlying securities in companies and fixed-income. The underlying securities include domestic and international companies of various sizes of capitalization. The asset allocation of the plan is reviewed on at least an annual basis. We made $0.3 million in contributions to the pension plans for the year ended December 31, 2021, and expect no contributions to be made to the pension plans in 2022. There were no employee contributions to the plans. The benefits expected to be paid in each year 2022–2026 are $6.4 million, $6.5 million, $7.1 million, $6.9 million and $7.0 million, respectively. The aggregate benefits expected to be paid in the five years from 2027–2031 are $35.5 million. The expected benefits are based on the same assumptions used to measure our benefit obligation at December 31, 2021 and include estimated future employee service. 401(k) Plans For the years ended December 31, 2021, 2020 and 2019, we sponsored a voluntary 401(k) Employee Retirement Savings Plans for eligible employees. Employees must be at least 21 years of age and eligibility to participate in the plan is immediate upon employment. Employee contributions are matched on a fully-vested basis by us up to a maximum of 6% of eligible compensation. Eligibility for the Company matching contribution begins on the first of the month following one year of employment. For the years ended December 31, 2021, 2020 and 2019, the 401(k) plans expense recognized was $4.8 million, $10.4 million and $9.6 million, respectively. Postretirement Medical Plan

Leases [Abstract]
Leases	Leases We lease certain retail stores, land, building and various equipment from others. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. Most leases include one or more options to renew, with renewal terms that can extend the lease term from one Some of our lease agreements include a rate based on equipment usage and others include a rate with fixed increases or inflationary indices based increase. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We rent or sublease certain real estate and equipment to third parties. Our sublease portfolio consists primarily of operating leases within our retail stores and crude storage equipment. As of December 31, 2021, $24.6 million of our net property, plant, and equipment balance is subject to an operating lease. This agreement does not include options for the lessee to purchase our leasing equipment, nor does it include any material residual value guarantees or material restrictive covenants. The agreement includes a one year renewal option and certain variable payment based on usage. The following table presents additional information related to our operating leases in accordance ASC 842, Leases ("ASC 842"): (in millions) Year Ended December 31, 2021 2020 Lease Cost Operating lease costs (1) $ 67.7 $ 64.0 Short-term lease costs (2) 33.9 24.4 Sublease income (5.8) (7.7) Net lease costs $ 95.8 $ 80.7 Other Information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases (1) $ (67.7) $ (64.0) Leased assets obtained in exchange for new operating lease liabilities $ 87.1 $ 58.1 Leased assets obtained in exchange for new financing lease liabilities $ 15.7 $ 5.6 December 31, 2021 December 31, 2020 Weighted-average remaining lease term (years) operating leases 4.7 5.2 Weighted-average remaining lease term (years) financing leases 6.6 2.9 Weighted-average discount rate operating leases (3) 6.3 % 6.4 % Weighted-average discount rate financing leases (3) 3.2 % 1.8 % (1) Includes an immaterial amount of financing lease cost.

Accounting Policies (Policies)

Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our consolidated financial statements include the accounts of Delek and its subsidiaries. All significant intercompany transactions and account balances have been eliminated in consolidation. We have evaluated subsequent events through the filing of this Form 10-K. Any material subsequent events that occurred during this time have been properly recognized or disclosed in our financial statements. Our consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics", NYSE:DKL), which is a variable interest entity ("VIE"). As the indirect owner of the general partner of Delek Logistics, we have the ability to direct the activities of this entity that most significantly impact its economic performance. We are also considered to be the primary beneficiary for accounting purposes for this entity and are Delek Logistics' primary customer. As Delek Logistics does not derive an amount of gross margin material to us from third parties, there is limited risk to Delek associated with Delek Logistics' operations. However, in the event that Delek Logistics incurs a loss, our operating results will reflect such loss, net of intercompany eliminations, to the extent of our ownership interest in this entity. The preparation of financial statements in conformity with United States ("U.S.") Generally Accepted Accounting Principles ("GAAP") and in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, all adjustments necessary for a fair presentation of the financial condition and the results of operations have been included. All adjustments are of a normal, recurring nature.
Reclassification	Reclassifications Certain immaterial reclassifications have been made to prior period presentation in order to conform to the current year presentation.
Segment Reporting	Segment Reporting Delek is an integrated downstream energy business based in Brentwood, Tennessee, and has three primary lines of business: petroleum refining; the transportation, storage and wholesale distribution of crude oil, intermediate and refined products; and convenience store retailing. For the periods presented, we have aggregated our operating segments into three reportable segments: Refining, Logistics and Retail. Operations that are not specifically included in the reportable segments are included in Corporate, Other and Eliminations, which consists of the following: • our corporate activities; • results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 11); • wholesale crude operations • Alon's asphalt terminal operations acquired as part of the Delek/Alon Merger; • results and assets of discontinued operations; and • intercompany eliminations. Decisions concerning the allocation of resources and assessment of operating performance are made based on this segmentation. Management measures the operating performance of each of the reportable segments based on the segment contribution margin. Segment contribution margin is defined as net revenues less cost of materials and other and operating expenses, excluding depreciation and amortization. All inter-segment transactions have been eliminated in consolidation. The refining segment operates high conversion, independent refineries located in Tyler, Texas (the "Tyler refinery"), El Dorado, Arkansas (the "El Dorado refinery"), Big Spring, Texas (the "Big Spring refinery"), Krotz Springs, Louisiana (the "Krotz Springs refinery"). In addition, the refining segment owns and operates three biodiesel facilities involved in the production of biodiesel fuels and related activities, located in Crossett, Arkansas, Cleburne, Texas and New Albany, Mississippi. The logistics segment owns and operates crude oil and refined products logistics and marketing assets. The retail segment markets gasoline, diesel and other refined petroleum products, and convenience merchandise through a network of company-operated retail fuel and convenience stores. Segment reporting is more fully discussed in Note 3.
Cash and Cash Equivalents	Cash and Cash Equivalents Delek maintains cash and cash equivalents in accounts with large, U.S. or multi-national financial institutions. All highly liquid investments purchased with a term of three months or less are considered to be cash equivalents. As of December 31, 2021 and 2020, these cash equivalents consisted primarily of bank money market accounts and bank certificates of deposit, as well as overnight investments in U.S. Government or its agencies' obligations and bank repurchase obligations collateralized by U.S. Government or its agencies' obligations.
Accounts Receivable	Accounts Receivable Accounts receivable primarily consists of trade receivables generated in the ordinary course of business, but may also include receivables on commodity sales contracts that are part of crude optimization and are, therefore, related to transactions that are reflected as reductions of cost of materials and other rather than revenue. Such other receivables are with the same or similar customers as our trade receivables, and are subject to the same characteristics regarding the nature, timing, pricing and risk. Delek recorded an allowance for doubtful accounts related to accounts receivable of $6.5 million and $7.2 million as of December 31, 2021 and 2020, respectively. Credit is extended based on evaluation of the customer’s financial condition. We perform ongoing credit evaluations of our customers and require letters of credit, prepayments or other collateral or guarantees as management deems appropriate. Allowance for doubtful accounts is based on a combination of historical experience and specific identification methods. Credit risk is minimized as a result of the ongoing credit assessment of our customers and a lack of concentration in our customer base. Credit losses are charged to allowance for doubtful accounts when deemed uncollectible. Our allowance for doubtful accounts is reflected as a reduction of accounts receivable in the consolidated balance sheets.
Inventory	Inventory Refinery crude oil, work-in-process, refined products, blendstocks and asphalt inventory for all of our operations, excluding the Tyler refinery and merchandise inventory in our Retail segment, are stated at the lower of cost determined using the FIFO basis or net realizable value. Cost of inventory at the Tyler refinery is determined using the LIFO inventory valuation method and inventory is stated at the lower of LIFO cost or market. Retail merchandise inventory consists of cigarettes, beer, convenience merchandise and food service merchandise and is stated at estimated cost as determined by the retail inventory method. We are not subject to concentration risk with specific suppliers, since our crude oil and refined products inventory purchases are commodities that are readily available from a large selection of suppliers.
Investment Commodities	Investment Commodities Investment commodities represent those commodities (generally crude oil) physically on hand as a result of trading activities with physical forward contracts where such crude will not be used (either directly in production or indirectly through inventory optimization) in the normal course of our refining business. Such investment commodities are maintained on a weighted average cost basis for determining realized gains and losses on physical purchases and sales under forward contracts, and ending balances are adjusted to fair value at each reporting date using published market prices of the commodity on the applicable exchange. The investment commodities are included in other current assets on the accompanying consolidated balance sheets and changes in fair value are recorded in other operating income in the accompanying consolidated statements of income.
Property, Plant and Equipment	Property, Plant and Equipment Assets acquired by Delek in conjunction with business acquisitions are recorded at estimated fair value at the acquisition date in accordance with the purchase method of accounting as prescribed in Accounting Standards Codification ("ASC") 805, Business Combinations ("ASC 805"). Other acquisitions of property and equipment are carried at cost. Betterments, renewals and extraordinary repairs that extend the life of an asset are capitalized. Maintenance and repairs are charged to expense as incurred. Delek owns certain fixed assets on leased locations and depreciates these assets and asset improvements over the lesser of management's estimated useful lives of the assets or the remaining lease term. Depreciation is computed using the straight-line method over management's estimated useful lives of the related assets, which are as follows: Years Building and building improvements 15-40 Refinery machinery and equipment 5-40 Pipelines and terminals 15-40 Retail store equipment and site improvements 7-40 Refinery turnaround costs 4-6 Automobiles 3-5 Computer equipment and software 3-10 Furniture and fixtures 5-15 Asset retirement obligation assets 15-50
Other Intangible Assets	Other Intangible AssetsOther intangible assets acquired in a business combination and determined to be finite-lived are amortized over their respective estimated useful lives. The finite-lived intangible assets are amortized on straight-line basis over the estimated useful lives of five
Property, Plant and Equipment and Other Intangibles Impairment	Property, Plant and Equipment and Other Intangibles Impairment Property, plant and equipment held and used and other intangibles are evaluated for impairment whenever indicators of impairment exist. In accordance with ASC 360, Property, Plant and Equipmen t ("ASC 360") and ASC 350, Intangibles - Goodwill and Other
Equity Method Investments	Equity Method InvestmentsFor equity investments that are not required to be consolidated under the variable or voting interest model, we evaluate the level of influence we are able to exercise over an entity’s operations to determine whether to use the equity method of accounting. Our judgment regarding the level of influence over an equity method investment includes considering key factors such as our ownership interest, participation in policy-making and other significant decisions and material intercompany transactions. Equity investments for which we determine we have significant influence are accounted for as equity method investments. Amounts recognized for equity method investments are included in equity method investments in our consolidated balance sheets and adjusted for our share of the net earnings and losses of the investee and cash distributions, which are separately stated in our consolidated statements of income and our consolidated statements of cash flows. We evaluate our equity method investments presented for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may be impaired.
Variable Interest Entities	Variable Interest Entities Our consolidated financial statements include the financial statements of our subsidiaries and variable interest entities, of which we are the primary beneficiary. We evaluate all legal entities in which we hold an ownership or other pecuniary interest to determine if the entity is a VIE. Variable interests can be contractual, ownership or other pecuniary interests in an entity that change with changes in the fair value of the VIE’s assets. If we are not the primary beneficiary, the general partner or another limited partner may consolidate the VIE, and we record the investment as an equity method investment.
Capitalized Interest	Capitalized InterestDelek capitalizes interest on capital projects associated with the refining and logistics segments.
Refinery Turnaround Costs	Refinery Turnaround CostsRefinery turnaround costs are incurred in connection with planned shutdowns and inspections of our refineries' major units to perform necessary repairs and replacements. Refinery turnaround costs are deferred when incurred, classified as property, plant and equipment and amortized on a straight-line basis over that period of time estimated to lapse until the next planned turnaround occurs. Refinery turnaround costs include, among other things, the cost to repair, restore, refurbish or replace refinery equipment such as vessels, tanks, reactors, piping, rotating equipment, instrumentation, electrical equipment, heat exchangers and fired heaters.
Goodwill and Impairment	Goodwill and Impairment Goodwill in an acquisition represents the excess of the aggregate purchase price over the fair value of the identifiable net assets. Goodwill is reviewed at least annually during the fourth quarter for impairment, or more frequently if indicators of impairment exist, such as disruptions in our business, unexpected significant declines in operating results or a sustained market capitalization decline. Goodwill is evaluated for impairment by comparing the carrying amount of the reporting unit to its estimated fair value. In accordance with ASU 2017-04, Goodwill and Other (Topic 350); Simplifying the Test for Goodwill Impairment , a goodwill impairment charge is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit.
Derivatives	Derivatives Delek records all derivative financial instruments, including any interest rate swap and cap agreements, fuel-related derivatives, over the counter ("OTC") future swaps, forward contracts and future RIN purchase and sales commitments that qualify as derivative instruments, at estimated fair value in accordance with the provisions of ASC 815, Derivatives and Hedging ("ASC 815"). Changes in the fair value of the derivative instruments are recognized in operations, unless we elect to apply and qualify for the hedging treatment permitted under the provisions of ASC 815 allowing such changes to be classified as other comprehensive income for cash flow hedges. We determine the fair value of all derivative financial instruments utilizing exchange pricing and/or price index developers such as Platts, Argus or OPIS. On a regular basis, Delek enters into commodity contracts with counterparties for the purchase or sale of crude oil, blendstocks, and various finished products. We evaluate these contracts under ASC 815 and do not measure at fair value if they qualify for, and we elect, the normal purchase / normal sale ("NPNS") exception. Delek's policy under the guidance of ASC 815-10-45, Derivatives and Hedging - Other Presentation Matters ("ASC 815-10-45"), is to net the fair value amounts recognized for multiple derivative instruments executed with the same counterparty and offset these values against the cash collateral arising from these derivative positions.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair values of financial instruments are estimated based upon current market conditions and quoted market prices for the same or similar instruments. Management estimates that the carrying value approximates fair value for all of Delek's assets and liabilities that fall under the scope of ASC 825, Financial Instruments ("ASC 825"). Delek also applies the provisions of ASC 825 as it pertains to the fair value option with respect to certain financial instruments. This option permits the election to carry financial instruments and certain other items similar to financial instruments at fair value on the balance sheet, with all changes in fair value reported in earnings. Delek applies the provisions of ASC 820, Fair Value Measurements and Disclosure
Inventory Supply and Offtake Obligations	Inventory Supply and Offtake ObligationsDelek has Supply and Offtake Agreements (the "Supply and Offtake Agreements" or the "J. Aron Agreements") with J. Aron & Company ("J. Aron") in connection with its El Dorado, Big Spring and Krotz Springs refineries, which provide a financing mechanism on contractual baseline inventory volumes and also revolving over and short volumes. We account for the market-indexed obligations under our Supply and Offtake Agreements as product (in this case, crude oil and refined product inventory) financing arrangements under the fair value option pursuant to ASC 825 and the fair value guidance provided by ASC 820, and recognize all changes in the fair value in cost of materials and other in the accompanying statements of income. During periods where we had fixed price components that were subject to interest rate risk and not market price risk, the changes in fair value of those components was recognized in interest expense. By electing the fair value option, the changes in fair value provide a natural economic hedge to our FIFO cost of sales recognition without having to bifurcate any embedded derivatives and consider the complex hedge accounting rules. See Notes 9 and 12 for further discussion.
Environmental Credits and Related Regulatory Obligations	Environmental Credits and Related Regulatory Obligations As part of our refining operations, we generate certain regulatory environmental credit obligations due to the U.S. Environmental Protection Agency (“EPA”) or other regulatory agencies. Additionally, we may generate, during the operation of our refining or other activities, or purchase on a market, environmental credits for purposes of ultimately meeting expected environmental credit obligations. These resultant net environmental credit obligations are financial instruments under ASC 825. For those financial instruments where (1) there are consistently available observable market inputs or market-corroborated inputs; and (2) there continues to be (or is reasonably expected to be) sustained liquidity in the applicable credits market, we generally apply the fair value option, as available pursuant to ASC 825. We recognize a current liability at the end of each reporting period in which we do not have sufficient environmental credits to cover the current environmental credits obligation (a “deficit”), and we recognize a current asset at the end of each reporting period in which we have generated or acquired environmental credits meeting our recognition criteria in excess of our current environmental credits obligation (a “surplus”). Any obligation surplus or deficit would be measured at fair value either directly through the observable inputs or indirectly through the market-corroborated inputs. The net cost of environmental credits used each period as well as changes to fair value attributable to our environmental credit obligations (surplus or deficit) are charged to cost of materials and other in the consolidated statements of income. Our environmental credit obligations predominantly relate to EPA’s Renewable Fuel Standard - 2 ("RFS-2"), which requires that certain refiners generate environmental credits, called Renewable Identification Numbers ("RINs"), by blending renewable fuels into the fuel products they produce, or else purchasing RINs on the market, and that such RINs shall be used to satisfy the related environmental credit obligation. Each of our refineries is an obligated party under RFS-2. To the extent that any of our refineries is unable to blend or produce renewable fuels to or generate or obtain sufficient RINs, it must purchase RINs to satisfy its annual requirement ("RINs Obligation"). To the extent that we have purchased RINs or transferred RINs to our refineries, each refinery’s RINs Obligation may be a surplus or deficit at the end of each reporting period (their respective “Net RINs Obligation”). Because our Net RINs Obligations exceed the RINs we are able to generate annually on a consolidated basis, and because we have the legal ability to transfer RINs generated or purchased through any of our entities to our obligated parties as needed, we view and manage the Company’s individual Net RINs Obligations, as well as any non-obligated party RINs holdings, on a consolidated basis. Therefore, the sum of our individual obligated parties’ Net RINs Obligations as well as RINs held by our non-obligated parties which meet our recognition criteria, comprises the Company’s “Consolidated Net RINs Obligation.” For all periods presented in these consolidated financial statements, the individual financial instruments relating to specific category and vintage requirements under RFS-2 comprising our Consolidated Net RINs Obligation are subject to market risk and meet the criteria set forth above. Therefore, we have elected to apply the fair value option to the individual financial instruments comprising our Consolidated Net RIN Obligation, using the fair value guidance provided by ASC 820. Recognition of production-related RINs Obligation expense reflects the accrual of our RINs Obligation based on the current period production using current market price of RINs. We record fair value adjustments to the RINs Obligation to reflect the ending market price of the underlying RINs relating to RINs Obligation incurred on previous production that is still outstanding. We also may have changes in fair value attributable to changes in other observable market inputs, such as changes in volumetric expectations for obligation years where the volumetric rates have not yet been enacted. Therefore, fair value adjustments represent adjustments for changes in observable inputs from what they were when we initially incurred and recorded the obligation. Other Related Transactions From time to time, Delek enters into future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our RINs Obligation. These future RINs commitment contracts meet the definition of derivative instruments under ASC 815, and are measured at fair value based on quoted prices from an independent pricing service. Changes in the fair value of these future RINs commitment contracts are recorded in cost of materials and other on the consolidated statements of income. See Note 11 for further information. Additionally, from time to time, we may elect to sell surplus environmental credits and contemporaneously enter into a corresponding obligation to repurchase substantially identical environmental credits at a future date to provide an additional source of short-term financing and to take advantage of market liquidity for holdings that are not currently required for operations. We account for such transactions as product financing arrangements. In such cases, the sale is not recognized, but rather the proceeds are treated as product financing proceeds where a corresponding product financing obligation is recorded, while the subsequent repurchase is treated as repayment of the product financing obligation, with the difference recorded as interest expense over the intervening period. Such transactions are included in our cash flows from financing transactions.
Self-Insurance Reserves	Self-Insurance Reserves Delek has varying deductibles or self-insured retentions on our workers’ compensation, general liability, automobile liability insurance and medical claims for certain employees with coverage above the deductibles or self-insured retentions in amounts management considers adequate. We maintain an accrual for these costs based on claims filed and an estimate of claims incurred but not reported. Differences between actual settlements and recorded accruals are recorded in the period identified.
Environmental Expenditures	Environmental Expenditures It is Delek's policy to accrue environmental and clean-up related costs of a non-capital nature when it is both probable that a liability has been incurred and the amount can be reasonably estimated. Environmental liabilities represent the current estimated costs to investigate and remediate contamination at sites where we have environmental exposure. This estimate is based on assessments of the extent of the contamination, the selected remediation technology and review of applicable environmental regulations, typically considering estimated activities and costs for 15 years, and up to 30 years if a longer period is believed reasonably necessary. Such estimates may require judgment with respect to costs, time frame and extent of required remedial and clean-up activities. Accruals for estimated costs from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study and include, but are not limited to, costs to perform remedial actions and costs of machinery and equipment that are dedicated to the remedial actions and that do not have an alternative use. Such accruals are adjusted as further information develops or circumstances change. We discount environmental liabilities to their present value if payments are fixed or reliably determinable. Expenditures for equipment necessary for environmental issues relating to ongoing operations are capitalized. Provisions for environmental liabilities generally are recognized in operating expenses. Changes in laws and regulations and actual remediation expenses compared to historical experience could significantly impact our results of operations and financial position. We believe the estimates selected, in each instance, represent our best estimate of future outcomes, but the actual outcomes could differ from the estimates selected.
Asset Retirement Obligation	Asset Retirement Obligations Delek initially recognizes liabilities which represent the fair value of a legal obligation to perform asset retirement activities, including those that are conditional on a future event, when the amount can be reasonably estimated. If a reasonable estimate cannot be made at the time the liability is incurred, we record the liability when sufficient information is available to estimate the liability’s fair value. In the refining segment, we have asset retirement obligations with respect to our refineries due to various legal obligations to clean and/or dispose of these assets at the time they are retired. In the logistics segment, these obligations relate to the required cleanout of the pipeline and terminal tanks and removal of certain above-grade portions of the pipeline situated on right-of-way property. In the retail segment, we have asset retirement obligations related to the removal of underground storage tanks and the removal of brand signage at owned and leased retail sites which are legally required under the applicable leases. The asset retirement obligation for storage tank removal on leased retail sites is accreted over the expected life of the owned retail site or the average retail site lease term.
Guarantees	Guarantees We account for guarantees pursuant to the guidance in ASC 460, Guarantees . The fair value of a noncontingent guarantee is determined and recorded as a liability at the time the guarantee is contractually executed, and the initial liability is subsequently reduced as we are released from exposure under the guarantee. We may amortize the noncontingent guarantee liability over the relevant time period, if one exists, based on the facts and circumstances surrounding each type of guarantee, including whether the risk underlying the guarantee diminishes over time. Otherwise, we will record changes in the fair value of the liability as they occur and can be reasonably estimated and will reverse the fair value liability when there is no further exposure under the guarantee. Changes to the guarantee liability are recognized in the consolidated income statement on the line item that best represents the nature of the guarantee. When the contingent performance on a guarantee becomes probable and the liability can be reasonably estimated, we accrue an additional liability for the amount that such liability exceeds the carrying value of the noncontingent guarantee, based on the facts and circumstances at that time.
Revenue Recognition	Revenue Recognition The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or by providing services to a customer. Refining Revenues for products sold are recorded at the point of sale upon delivery of product, which is the point at which title to the product is transferred, the customer has accepted the product and the customer has significant risks and rewards of owning the product. We typically have a right to payment once control of the product is transferred to the customer. Transaction prices for these products are typically at market rates for the product at the time of delivery. Payment terms require customers to pay shortly after delivery and do not contain significant financing components. Logistics Revenues for products sold are generally recognized upon delivery of the product, which is when title and control of the product is transferred. Transaction prices for these products are typically at market rates for the product at the time of delivery. Service revenues are recognized as crude oil, intermediate and refined product are shipped through, delivered by or stored in our pipelines, trucks, terminals and storage facility assets, as applicable. We do not recognize product revenues for these services as the product does not represent a promised good in the context of ASC 606, Revenue from Contracts with Customers ("ASC 606"). All service revenues are based on regulated tariff rates or contractual rates. Payment terms require customers to pay shortly after delivery and do not contain significant financing components. Retail Fuel and merchandise revenue is recognized at the point of sale, which is when control of the product is transferred to the customer. Payments from customers are received at the time sales occur in cash or by credit or debit card. We derive service revenues from the sale of lottery tickets, money orders, car washes and other ancillary product and service offerings. Service revenue and related costs are recorded at gross amounts or net amounts, as appropriate, in accordance with the principal versus agent provisions in ASC 606. Other In the first quarter of 2020, we began selling crude barrels through supply agreements predominantly in the gulf coast region. The transaction price for these products is based on contractual rates. Revenue is recognized based on consideration specified in such agreements when performance obligations are satisfied by transferring control of crude oil to the customer. The transaction prices of our contracts with customers are either fixed or variable, with variable pricing generally based on various market indices. For our contracts that include variable consideration, we utilize the variable consideration allocation exception, whereby the variable consideration is only allocated to the performance obligations that are satisfied during the period. Refer to Note 3 for disclosure of our revenue disaggregated by segment, as well as a description of our reportable segment income. Credit Losses Under ASU 2016-13, Financial Instruments - Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), as codified in ASC 326, Financial Instruments - Credit Losses ("ASC 326"), we have applied the expected credit loss model for recognition and measurement of impairments in financial assets measured at amortized cost or at fair value through other comprehensive income including accounts receivables. The expected credit loss model is also applied for notes receivables and contractual holdbacks to which ASU 2016-13 applies and which are not accounted for at fair value through profit or loss. The loss allowance for the financial asset is measured at an amount equal to the lifetime expected credit losses. If the credit risk on the financial asset has decreased significantly since initial recognition, the loss allowance for
Cost of Materials and Other and Operating Expenses	Cost of Materials and Other and Operating Expenses For the refining segment, cost of materials and other includes the following: • the direct cost of materials (such as crude oil and other refinery feedstocks, refined petroleum products and blendstocks, and ethanol feedstocks and products) that are a component of our products sold; • costs related to the delivery (such as shipping and handling costs) of products sold; • costs related to our environmental credit obligations to comply with various governmental and regulatory programs (such as the cost of RINs as required by the EPA's Renewable Fuel Standard and emission credits under various cap-and-trade systems); and • gains and losses on our commodity derivative instruments. Operating expenses for the refining segment include the costs to operate our refineries and biodiesel facilities, excluding depreciation and amortization. These costs primarily include employee-related expenses, energy and utility costs, catalysts and chemical costs, and repairs and maintenance expenses. For the logistics segment, cost of materials and other includes the following: • all costs of purchased refined products, additives and related transportation of such products, • costs associated with the operation of our trucking assets, which primarily include allocated employee costs and other costs related to fuel, truck leases and repairs and maintenance, • the cost of pipeline capacity leased from a third-party, and • gains and losses related to our commodity hedging activities. Operating expenses for the logistics segment include the costs associated with the operation of owned terminals and pipelines and terminalling expenses at third-party locations, excluding depreciation and amortization. These costs primarily include outside services, allocated employee costs, repairs and maintenance costs and energy and utility costs. Operating expenses related to the wholesale business are excluded from cost of sales because they primarily relate to costs associated with selling the products through our wholesale business. For the retail segment, cost of materials and other comprises the costs related to specific products sold at retail sites, primarily consisting of motor fuels and merchandise. Retail fuel cost of sales represents the cost of purchased fuel, including transportation costs. Merchandise cost of sales includes the delivered cost of merchandise purchases, net of merchandise rebates and commissions. Operating expenses related to the retail business include costs such as wages of employees, lease expense, utility expense and other costs of operating the stores, excluding depreciation and amortization, and are excluded from cost of sales because they primarily relate to costs associated with selling the products through our retail sites. Depreciation and amortization is separately presented in our statement of income and disclosed by reportable segment in Note 3.
Interest Expense	Interest Expense Interest expense includes interest expense on debt, letters of credit, financing fees (including certain J. Aron fees associated with our Supply and Offtake Agreements), the amortization, net of accretion, of debt discounts or premium and amortization of deferred debt issuance costs, and interest rate hedge settlements, if any, but excludes capitalized interest. Original issuance discount and debt issuance costs are amortized ratably over the term of the related debt when it is not materially different from the effective interest method.
Sales, Use and Excise Taxes	Sales, Use and Excise TaxesDelek's policy is to exclude from revenue all taxes assessed by a governmental authority, including sales, use and excise taxes, that are both imposed on and concurrent with a specific revenue-producing transaction and collected from a customer.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs associated with our revolving credit facilities are included in other non-current assets in the accompanying consolidated balance sheets. Deferred financing costs associated with our term loan facilities are included as a reduction to the associated debt balance in the accompanying consolidated balance sheets. These costs represent expenses related to issuing our long-term debt and obtaining our lines of credit and are amortized ratably over the remaining term of the respective financing when it is not materially different from the effective interest method and included in interest expense in the accompanying consolidated statements of income. See Note 10 for further information.
Advertising Cost	Advertising CostsDelek expenses advertising costs as the advertising space is utilized.
Leases	Leases In accordance with ASC 842-20, Leases - Lessee ("ASC 842-20"), we classify leases with contractual terms longer than twelve months as either operating or finance. Finance leases are generally those leases that are highly specialized or allow us to substantially utilize or pay for the entire asset over its useful life. All other leases are classified as operating leases. Delek leases land, buildings and various equipment under primarily operating lease arrangements, most of which provide the option, after the initial lease term, to renew the leases. Some of these lease arrangements include fixed lease rate increases, while others include lease rate increases based upon such factors as changes, if any, in defined inflationary indices. For all leases that include fixed rental rate increases, these are included in our fixed lease payments. Our leases may include variable payments, based on changes on price or other indices, that are expensed as incurred. Delek calculates the total lease expense for the entire noncancelable lease period, considering renewals for all periods for which it is reasonably certain to be exercised, and records lease expense on a straight-line basis in the accompanying consolidated statements of income. Accordingly, a lease liability is recognized for these leases and is calculated to be the present value of the fixed lease payments, as defined by ASC 842-20, using a discount rate based on our incremental borrowing rate. A corresponding right-of-use asset is recognized based on the lease liability and adjusted for certain costs and prepayments. The right-of-use asset is amortized over the noncancelable lease period, considering renewals for all periods for which it is reasonably certain to be exercised. See Note 23 for further information.
Income Taxes	Income Taxes Income taxes are accounted for under the provisions of ASC 740, Income Taxes ("ASC 740"). This standard generally requires Delek to record deferred income taxes for the differences between the book and tax bases of its assets and liabilities, which are measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. Deferred income tax expense or benefit represents the net change during the year in our deferred income tax assets and liabilities, exclusive of the amounts held in other comprehensive income. ASC 740 also prescribes a comprehensive model for how companies should recognize, measure, present and disclose in their financial statements uncertain tax positions taken or expected to be taken on a tax return and prescribes the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. Finally, ASC 740 requires an annual tabular roll-forward of unrecognized tax benefits. On March 27, 2020, the Coronavirus Aid Relief, and Economic Security Act (the "CARES Act") was enacted into law. The CARES Act includes several significant provisions for corporations, including the usage of net operating losses, interest deductions and payroll benefits. The Biden administration has proposed several corporate tax increases, including raising the U.S. corporate income tax rate and a global minimum tax, that, if enacted, may have an adverse impact on our tax liability. These proposals include changes to the existing framework in respect of income taxes, as well as new types of non-income taxes which could apply to our business.
Equity-Based Compensation	Equity-Based Compensation ASC 718, Compensation - Stock Compensation ("ASC 718"), requires the cost of all share-based payments to employees, including grants of employee stock options, to be recognized in the income statement and establishes fair value as the measurement objective in accounting for share-based payment arrangements. ASC 718 requires the use of a valuation model to calculate the fair value of stock-based awards on the date of grant. Delek uses the Black-Scholes-Merton option-pricing model to determine the fair value of stock option and stock appreciation right (SAR) awards. Restricted stock units ("RSUs") are valued based on the fair market value of the underlying stock on the date of grant. Performance-based RSUs ("PRSUs") include a market condition based on the Company's total shareholder return over the performance period and are valued using a Monte-Carlo simulation model. We record compensation expense for these awards based on the grant date fair value of the award, recognized ratably over the measurement period. Vested RSUs and PRSUs are not issued until the minimum statutory withholding requirements have been remitted to us for payment to the taxing authority. As a result, the actual number of shares accounted for as issued may be less than the number of RSUs vested, due to any withholding amounts which have not been remitted. We generally recognize compensation expense related to stock-based awards with graded or cliff vesting on a straight-line basis over the vesting period. It is our practice to issue new shares when share-based awards are exercised. Our equity-based compensation expense includes estimates for forfeitures and volatility based on our historical experience. If actual forfeitures differ from our estimates, we adjust equity-based compensation expense accordingly.
Postretirement Benefits	Postretirement Benefits In connection with the Delek/Alon Merger, we assumed defined benefit pension and postretirement medical plans for certain former Alon employees. We recognize the underfunded status of our defined benefit pension and postretirement medical plans as a liability. Changes in the funded status of our defined benefit pension and postretirement medical plans are recognized in other comprehensive income in the period when the changes occur. The funded status represents the difference between the projected benefit obligation and the fair value of the plan assets. The projected benefit obligation is the present value of benefits earned to date by plan participants, including the effect of assumed
