⁽¹⁾  Net revenues and cost of materials and other for the three and six months ended June 30, 2018 reflect a correction of an intercompany elimination which resulted in an increase in those accounts of $73.4 million not previously reflected on the unaudited consolidated financial statements in our June 30, 2018 Quarterly Report on Form 10-Q filed on August 9, 2018. Such amounts are not considered material to the financial statements and had no impact to operating income or net income for those periods. See Note 23 to our annual audited consolidated financial statements included in Part II, Item 8 of our 2018 Annual Report on Form 10-K, as amended and filed on June 27, 2019, for further discussion.

⁽²⁾  Income tax expense for the six months ended June 30, 2018 reflects a correction made in our 2018 Annual Report on Form 10-K (as originally filed on March 1, 2019) to record additional deferred tax expense totaling $5.5 million related to the recognition of a valuation allowance on deferred tax assets recognized in connection with the Big Spring Logistic Assets Acquisition (see Note 5) not previously reported in our June 30, 2018 Quarterly Report on Form 10-Q filed on August 09, 2018. Such amount is not considered material to the financial statements or the trend of earnings for that period. See Note 23 to our annual audited consolidated financial statements included in Part II, Item 8 of our 2018 Annual Report on Form 10-K, as amended and filed on June 27, 2019, for further discussion.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 - Organization and Basis of Presentation

Delek US Holdings, Inc. operates through its consolidated subsidiaries, which include Delek US Energy, Inc. (and its subsidiaries) and Alon USA Energy, Inc. ("Alon") (and its subsidiaries).

Effective July 1, 2017 (the "Effective Time"), we acquired the outstanding common stock of Alon (previously listed under NYSE: ALJ) (the "Delek/Alon Merger", as further discussed in Note 2), resulting in a new post-combination consolidated registrant renamed as Delek US Holdings, Inc. (“New Delek”), with Alon and the previous Delek US Holdings, Inc. (“Old Delek”) surviving as wholly-owned subsidiaries. New Delek is the successor issuer to Old Delek and Alon pursuant to Rule 12g-3(c) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). In addition, as a result of the Delek/Alon Merger, the shares of common stock of Old Delek and Alon were delisted from the New York Stock Exchange ("NYSE") in July 2017, and their respective reporting obligations under the Exchange Act were terminated.

Unless otherwise indicated or the context requires otherwise, the disclosures and financial information included in this report for the periods prior to July 1, 2017 reflect that of Old Delek, and the disclosures and financial information included in this report for the periods beginning July 1, 2017 reflect that of New Delek. The terms "we," "our," "us," "Delek" and the "Company" are used in this report to refer to Old Delek and its consolidated subsidiaries for the periods prior to July 1, 2017, and New Delek and its consolidated subsidiaries for the periods on or after July 1, 2017, unless otherwise noted. New Delek's Common Stock is listed on the NYSE under the symbol "DK."

Our condensed consolidated financial statements include the accounts of Delek and its subsidiaries. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited consolidated financial statements included in our Annual Report on Form 10-K as amended and filed with the Securities and Exchange Commission ("SEC") on June 27, 2019 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2018 included in our Annual Report on Form 10-K.

Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics"), which is a variable interest entity. 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.

In the opinion of management, all adjustments necessary for a fair presentation of the financial condition and the results of operations for the interim periods have been included. All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year.

Reclassifications

Certain prior period amounts have been reclassified in order to conform to the current period presentation. Additionally, certain changes to presentation of the prior period statements of income have been made in order to conform to the current period presentation, primarily relating to the addition of a subtotal entitled 'cost of sales' which includes all costs directly attributable to the generation of the related revenue, as defined by GAAP, and the retitling of what was previously referred to as 'cost of goods sold' to 'cost of materials and other'. In connection with this change in presentation, we revised our related accounting policy, as presented in our 2018 Annual Report on Form 10-K.

New Accounting Pronouncements Adopted During 2019

Accounting Standards Update ("ASU") 2016-02, Leases

In February 2016, the Financial Accounting Standards Board (the "FASB") issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial condition for all leases with terms longer than one year. The guidance was subsequently amended to consider the impact of practical expedients and provide additional clarifications. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We adopted the new lease standard on January 1, 2019. We elected the package of practical expedients which, among other things, allows us to carry forward the historical lease classification. For certain lease classes, we have elected the practical expedient not to separate lease and non-lease components, which allows us to combine the components if certain criteria are met. Further, we elected the optional transition method, which allows us to recognize a cumulative-effect adjustment to the opening balance sheet of retained earnings at the date of adoption and to not recast our comparative periods. We have not elected the hindsight practical expedient, which would have allowed us to use hindsight in determining the reasonably certain lease term. The adoption of the lease accounting guidance had no impact on January 1, 2019 retained earnings and resulted in the recognition of a $211.0 million lease liability and a corresponding right-of-use asset on our consolidated balance sheet. The adoption did not have a material impact on our consolidated income statement. See Note 20 for further information.

ASU 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities

In August 2017, the FASB issued guidance to better align financial reporting for hedging activities with the economic objectives of those activities for both financial (e.g., interest rate) and commodity risks. The guidance was intended to create more transparency in the presentation of financial results, both on the face of the financial statements and in the footnotes, and simplify the application of hedge accounting guidance. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Companies are required to apply the guidance on a modified retrospective transition method in which the cumulative effect of the change is recognized within equity in the consolidated balance sheet as of the date of adoption. We adopted this guidance on January 1, 2019 and the adoption did not have a material impact on our business, financial condition or results of operations. See Note 11 for further information.

Accounting Pronouncements Not Yet Adopted

ASU 2018-15, Intangible - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

In August 2018, the FASB issued guidance related to customers’ accounting for implementation costs incurred in a cloud computing arrangement that is considered a service contract. This pronouncement aligns the requirements for capitalizing implementation costs in such arrangements with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued. Entities can choose to adopt the new guidance prospectively or retrospectively. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition and results of operations.

ASU 2018-14, Compensation - Changes to the Disclosure Requirements for Defined Benefit Plans

In August 2018, the FASB issued guidance related to disclosure requirements for defined benefit plans. The pronouncement eliminates, modifies and adds disclosure requirements for defined benefit plans. The pronouncement is effective for fiscal years ending after December 15, 2020, and early adoption is permitted. We expect to adopt this guidance on or before the effective date and do not expect adopting this new guidance will have a material impact on our business, financial condition or results of operations.

ASU 2018-13, Fair Value Measurement - Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued guidance related to disclosure requirements for fair value measurements. The pronouncement eliminates, modifies and adds disclosure requirements for fair value measurements. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. We expect to adopt this guidance on or before the effective date and do not expect adopting this new guidance will have a material impact on our business, financial condition or results of operations.

ASU 2016-13, Financial Instruments - Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued guidance requiring the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Organizations will now use forward-looking information to better inform their credit loss estimates. This guidance is effective for interim and annual periods beginning after December 15, 2019. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition and results of operations.

Note 2 - Acquisitions

In January 2017, we announced that Old Delek (and various related entities) entered into a merger agreement with Alon, as amended (the "Merger Agreement"). The related Merger (as previously defined, the "Delek/Alon Merger") was effective July 1, 2017 (as previously defined, the “Effective Time”), resulting in a new post-combination consolidated registrant renamed as Delek US Holdings, Inc. (as previously defined, “New Delek”), with Alon and Old Delek surviving as wholly-owned subsidiaries of New Delek. New Delek is the successor issuer to Old Delek and Alon pursuant to Rule 12g-3(c) under the Exchange Act, as amended. In addition, as a result of the Delek/Alon Merger, the shares of common stock of Old Delek and Alon were delisted from the NYSE in July 2017, and their respective reporting obligations under the Exchange Act were terminated.

In connection with the Delek/Alon Merger, Alon, New Delek and U.S. Bank National Association, as trustee (the “Trustee”) entered into a First Supplemental Indenture (the “Supplemental Indenture”), effective as of July 1, 2017, which provided for Alon's 3.00% Convertible Senior Notes due 2018, which were previously convertible into Alon Common Stock, to thereafter be convertible into New Delek Common Stock based on the exchange rate applied in the Delek/Alon Merger (the “Convertible Notes”). Additionally, in connection with the Convertible Notes, Alon also entered into equity instruments, including call options (the "Call Options") and warrants (the "Warrants"), designed, in combination, to hedge a portion of the risk associated with the potential exercise of the conversion feature of the Convertible Notes and to mitigate the dilutive effect of such potential conversion. These instruments were also exchanged in connection with the Delek/Alon Merger into instruments that were indexed to New Delek Common Stock. See Note 10 for further discussion of these instruments and subsequent activity.

The Delek/Alon Merger was accounted for using the acquisition method of accounting, which requires, among other things, that assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the acquisition date. Transaction costs incurred by the Company in connection with the Delek/Alon Merger totaled $1.8 million and $6.6 million for the three and six months ended June 30, 2018, respectively. Such costs were included in general and administrative expenses in the accompanying condensed consolidated statements of income.

The final allocation of the aggregate purchase price (which was finalized as of June 30, 2018) is summarized as follows (in millions), and is inclusive of our discontinued Paramount and Long Beach, California refinery and California renewable fuels facility operations (collectively, the "California Discontinued Entities," discussed in Note 7):

Delek common stock issued	19,250,795
Ending price per share of Delek Common Stock immediately before the Effective Time	$	26.44
Total value of common stock consideration			$	509.0
Additional consideration (1)			21.7
Fair value of Delek's pre-existing equity method investment in Alon (2)			449.0
			979.7
Less: Fair value of net assets acquired			109.0
Goodwill (excess of purchase price over fair value of net assets acquired)			$	870.7

⁽¹⁾   Additional consideration includes the fair value of certain equity instruments originally indexed to Alon stock that were exchanged for instruments indexed to New Delek's stock, as well as the fair value of certain share-based payments that were required to be exchanged for awards indexed to New Delek's stock in connection with the Delek/Alon Merger.

⁽²⁾ The fair value of Delek's pre-existing equity method investment in Alon was based on the quoted market price of shares of Alon.

During the three and six months ended June 30, 2018, certain immaterial catch-up adjustments were recorded related to accretion of environmental liabilities and amortization of leasehold intangibles identified and valued during the final months of the measurement period.

Note 3 - Segment Data

We aggregate our operating units 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 consist of the following: our corporate activities; results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 11); Alon's asphalt terminal operations acquired as part of the Delek/Alon Merger and subsequently substantially disposed in the second quarter of 2018 (see Note 7 for further discussion); the California Discontinued Entities which were acquired as part of the Delek/Alon Merger and subsequently disposed over the first seven months of 2018 (see Note 7 for further discussion); and intercompany eliminations.

Notes to Condensed Consolidated Financial Statements (Unaudited)

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.

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 June 30, 2019, including the 75,000 bpd Tyler, Texas refinery (the "Tyler refinery"), the 80,000 bpd El Dorado, Arkansas refinery (the "El Dorado refinery"), the 73,000 bpd Big Spring, Texas refinery (the "Big Spring refinery"), and the 74,000 bpd Krotz Springs, Louisiana refinery (the "Krotz Springs refinery"), as well as a non-operating refinery located in Bakersfield, California. The refining segment also owns and operates two biodiesel facilities involved in the production of biodiesel fuels and related activities, located in Crossett, Arkansas and Cleburn, Texas. The refining segment's petroleum-based products are marketed primarily in the south central, southwestern and western regions of the United States, and the refining 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, we sell motor fuels through our wholesale distribution network on an unbranded basis.

Our refining segment has service agreements with our logistics segment, which, among other things, requires the refining segment to pay service fees based on the number of gallons sold and to share a portion of the margin achieved in return for providing marketing, sales and customer services at the Tyler refinery, and effective March 1, 2018, at the Big Spring refinery (see Note 5 for further discussion regarding the Big Spring marketing agreement). These intercompany transaction fees in regards to the Tyler refinery were $5.1 million and $9.9 million during the three and six months ended June 30, 2019, respectively, and $5.5 million and $10.5 million during the three and six months ended June 30, 2018, respectively. The intercompany transaction fees in regards to the Big Spring refinery were $3.4 million and $7.0 million for the three and six months ended June 30, 2019, respectively, and $3.2 million and $4.3 million for the three and six months ended June 30, 2018, respectively. Additionally, the refining segment purchases finished product and pays crude transportation, terminalling and storage fees to the logistics segment for the utilization of pipeline, terminal and storage assets, including, effective March 1, 2018, those related to the Big Spring Logistic Assets Acquisition discussed further in Note 5. These costs and fees were $52.2 million and $104.4 million during the three and six months ended June 30, 2019, respectively, and $43.6 million and $97.9 million during the three and six months ended June 30, 2018, respectively. The logistics segment also sold $0.4 million and $0.8 million of renewable identification numbers ("RINs") to the refining segment during the three and six months ended June 30, 2019, respectively, and $0.7 million and $2.0 million during the three and six months ended June 30, 2018, respectively. The refining segment recorded refined product sales revenues from the retail segment of $101.7 million and $191.9 million during the three and six months ended June 30, 2019, respectively, and $118.9 million and $218.4 million during the three and six months ended June 30, 2018, respectively. The refining segment includes refined product sales revenues from our logistics segment of $73.2 million and $152.6 million during the three and six months ended June 30, 2019, respectively, and $99.5 million and $181.8 million during the three and six months ended June 30, 2018, respectively. The refining segment also includes sales revenues of $40.4 million and $55.4 million from sales of asphalt and refined product to entities included in corporate, other and eliminations during the three and six months ended June 30, 2019, respectively, and $7.7 million and $11.1 million during the three and six months ended June 30, 2018.

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. The logistics segment is currently managing a long-term capital project on our behalf for the construction of a gathering system in the Permian Basin. Pursuant to the agreement(s) governing these services, the logistics segment received management fees of $1.1 million and $2.8 million during the three and six months ended June 30, 2019, respectively, from corporate for the management of this project. The logistics segment incurs some of the costs in connection with the construction of the assets and is subsequently reimbursed by corporate.

Our retail segment consists of approximately 263 owned and leased convenience store sites as of June 30, 2019, located primarily in central and west Texas and New Mexico. These convenience stores typically offer various grades of gasoline and diesel primarily 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 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. In November 2018, we terminated the license agreement with 7-Eleven, Inc. and the terms of such termination require the removal of all 7-Eleven branding on a store-by-store basis by the earlier of December 31, 2021 or the date upon which our last 7-Eleven store is de-identified or closed. 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 pursuant to the termination. In connection with certain strategic initiatives, we closed or sold 20 under-performing or non-strategic store locations during the six months ended June 30, 2019. As a result of these transactions, we expect to receive total proceeds of $9.9 million, of which $5.8 million was received in the six months ended June 30, 2019, and recognized gains of a nominal amount and $2.1 million during the three and six months ended June 30, 2019,

Note 4 - Earnings (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 periods presented, we have outstanding various equity-based compensation awards that are considered in our diluted EPS calculation (when to do so would be dilutive), and is inclusive of awards disclosed in Note 17 to these condensed 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. Additionally, in connection with the Delek/Alon Merger, we assumed certain equity instruments, including conversion options (associated with the Convertible Notes) and Warrants, that may be dilutive (see discussion of these instruments in Note 10). The Convertible Notes conversion options were dilutive during the period they were outstanding when the incremental EPS calculated by dividing the increase in income associated with the elimination of interest expense on the convertible debt, net of tax, by the number of shares that would be issued upon conversion using the treasury stock method (which is applicable because of the cash settlement feature associated with the underlying principal) is dilutive to the overall diluted EPS calculation. The Warrants are generally dilutive during the period they are outstanding when the market price of the underlying indexed share of common stock is in excess of the exercise price. All such instruments that may otherwise be dilutive may not be dilutive when there is a net loss for the period. On September 17, 2018, Delek settled the Convertible Notes for a combination of cash and shares of New Delek Common Stock (See Note 10) and in November 2018, Delek entered into Warrant Unwind Agreements (the "Unwind Agreements" - See Note 10) with the holders of our outstanding common stock warrants; therefore, these instruments were only potentially dilutive for EPS for the three and six months ended June 30, 2018.

Note 5 - Delek Logistics and the Alon Partnership

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 June 30, 2019, we owned a 61.4% limited partner interest in Delek Logistics, consisting of 15,294,046 common

18 |

Notes to Condensed Consolidated Financial Statements (Unaudited)

units, and a 94.6% interest in Delek Logistics GP, LLC, which owns the entire 2.0% general partner interest, consisting of 498,312 general partner units, in Delek Logistics and all of the incentive distribution rights.

The limited partner interests in Delek Logistics not owned by us are reflected in net income attributable to non-controlling interest in the accompanying condensed consolidated statements of income and in non-controlling interest in subsidiaries in the accompanying condensed consolidated balance sheets.

In March 2018, a subsidiary of Delek Logistics completed the acquisition from a subsidiary of Delek (the "Alon Partnership") of storage tanks and terminals that support the Big Spring refinery (the "Big Spring Logistic Assets Acquisition"), which included the execution of related commercial agreements. In addition, a new marketing agreement was entered into between the subsidiary of Delek Logistics and the Alon Partnership pursuant to which the subsidiary of Delek Logistics provides marketing services for product sales from the Big Spring refinery. The cash paid for the transferred assets was $170.8 million, subject to certain post-closing adjustments, and the cash paid for the marketing agreement was $144.2 million. The transactions were financed with borrowings under the 2014 Facility revolving credit agreement (as defined in Note 10). Additionally, the transaction resulted in the creation of a deferred tax asset related to the tax-book basis difference in the sold assets totaling $98.8 million, against which we have recorded a valuation allowance totaling $5.5 million for the portion of the deferred tax asset that relates to basis difference attributable to the non-controlling interest and therefore may not be realizable. Prior periods have not been recast in our Segment Data Note 3, as these assets did not constitute a business in accordance with ASU 2017-01, Clarifying the Definition of a Business, and were accounted for as acquisitions of assets between entities under common control.

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, including new agreements related to the Big Spring Logistic Assets Acquisition. The revenues and expenses associated with these agreements are eliminated in consolidation.

Delek Logistics is a variable interest entity, as defined under GAAP, and is consolidated into our condensed consolidated financial statements, representing our logistics segment. Exclusive of intercompany balances and the marketing agreement intangible asset between Delek Logistics and Delek which are eliminated in consolidation, the Delek Logistics condensed consolidated balance sheets as presented below are included in the condensed consolidated balance sheets of Delek (unaudited, in millions).

Notes to Condensed Consolidated Financial Statements (Unaudited)

Alon Partnership

As part of the Delek/Alon Merger, we acquired a majority interest in the Alon Partnership, which owns the assets and conducts the operations of the Big Spring refinery and the associated integrated wholesale marketing operations. On February 7, 2018 (the "Merger Date"), Delek acquired from the Alon Partnership all of the outstanding limited partner units that Delek did not already own in an all-equity transaction (the "Alon Partnership Merger"). Delek owned approximately 51.0 million limited partner units of the Alon Partnership, or approximately 81.6% of the outstanding units, immediately prior to the Merger Date. Under terms of the merger agreement, the owners of the remaining outstanding units in the Alon Partnership that Delek did not own immediately prior to the Merger Date received a fixed exchange ratio of 0.49 shares of New Delek common stock for each limited partner unit of the Alon Partnership, resulting in the issuance of approximately 5.6 million shares of New Delek common stock to the public unitholders of the Alon Partnership. Because the transaction represented a combination of ownership interests under common control, the transfer of equity from non-controlling interest to owned interest (additional paid-in capital) was recorded at carrying value and no gain or loss was recognized in connection with the transaction. Additionally, book-tax basis difference was created as a result of the transaction that resulted in a deferred tax asset of approximately $13.5 million, net of a valuation allowance on certain state income tax components, that also increased additional paid-in capital. Transaction costs incurred by the Company in connection with the Alon Partnership Merger totaled approximately $3.0 million for the six months ended June 30, 2018, none of which were recorded in the second quarter of 2018. Such costs were included in general and administrative expenses in the accompanying condensed consolidated statements of income.

Prior to the Merger Date, the Alon Partnership was a variable interest entity for which Delek was the primary beneficiary. As of June 30, 2019 and December 31, 2018, the Alon Partnership is included in Delek's condensed consolidated balance sheet as a wholly-owned subsidiary.

Note 6 - Equity Method Investments

In May 2019, Delek Logistics, through its wholly owned indirect subsidiary Delek Logistics Pipeline, LLC (“Delek Logistics 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, Delek Logistics 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 Delek Logistics 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, with an expansion project planned to increase the pipeline capacity, which is expected to be completed during the first half of 2020. Delek Logistics contributed an additional $3.5 million related to such expansion project in May 2019.

Delek Logistics also has two joint ventures that own and operate logistics assets, and which serve third parties and subsidiaries of Delek. As of June 30, 2019 and December 31, 2018, Delek Logistics' investment balances in these joint ventures totaled $241.6 million and $104.8 million, respectively, and were accounted for using the equity method.

Delek Renewables, LLC, a wholly-owned subsidiary of Delek, has 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 June 30, 2019 and December 31, 2018, Delek Renewables, LLC's investment balance in this joint venture was $4.0 million and $2.4 million, respectively, and was accounted for using the equity method. The investment in this joint venture is reflected in the refining segment.

Effective with the Delek/Alon Merger, we acquired a 50% interest in two joint ventures that own asphalt terminals located in Fernley, Nevada, and Brownwood, Texas. On May 21, 2018, Delek sold its 50% interest in the asphalt terminal located in Fernley, Nevada. See Note 7 for further discussion. As of June 30, 2019 and December 31, 2018, Delek's investment balance in the Brownwood, Texas joint venture was $28.0 million and $23.1 million, respectively. This investment is accounted for using the equity method and is included as part of total assets in corporate, other and eliminations in our segment disclosure.

Note 7 - Discontinued Operations and Assets Held for Sale

Asphalt Terminals Held for Sale

On February 12, 2018, Delek announced it had reached a definitive agreement to sell certain assets and operations of four asphalt terminals (included in corporate, other and eliminations in our segment disclosure), as well as an equity method investment in an additional asphalt terminal located in Femley, Nevada, to an affiliate of Andeavor. On May 21, 2018, Delek completed the transaction and received net proceeds of approximately $110.8 million, inclusive of the $75.0 million base proceeds as well as certain working capital adjustments. The assets associated with the owned terminals met the definition of held for sale pursuant to ASC 360 as of February 1, 2018, but did not meet the definition of discontinued operations pursuant to ASC 205-20, Presentation of Financial Statements - Discontinued Operations ("ASC 205-20"), as the sale of these asphalt assets did not represent a strategic shift that would have a major effect on the entity's operations and

Notes to Condensed Consolidated Financial Statements (Unaudited)

financial results. Accordingly, depreciation ceased as of February 1, 2018, and the assets to be sold were reclassified to assets held for sale as of that date and were written down to the estimated fair value less costs to sell, resulting in an impairment loss on assets held for sale of $27.5 million for the six months ended June 30, 2018 (none for the three months ended June 30, 2018). All goodwill associated with the asphalt operations sold was written off in connection with the impairment charge discussed above. In connection with the completion of the sale transaction in the second quarter of 2018, we recognized a gain of approximately $13.2 million, resulting primarily from the recognition of certain additional proceeds at closing associated with the asphalt terminals which were not previously determinable/probable and the recognition of the gain on the sale of the joint venture which was not previously recognized as held for sale (as it did not meet the criteria).

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 and our California renewable fuels facility (as previously defined, the "California Discontinued Entities"). Such operations were designated and reported as discontinued operations. On March 16, 2018, Delek sold to World Energy, LLC (i) all of Delek’s membership interests in the California renewable fuels facility ("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. Upon final settlement (excluding contingent components), Delek expects to receive net cash proceeds of approximately $85.2 million, which includes a post-closing working capital settlement, Delek’s portion of the biodiesel tax credit for 2017 and certain customary adjustments. The sale resulted in a loss on sale of discontinued operations totaling approximately $41.4 million of which $41.2 million was recorded during the six months ended June 30, 2018 (none for the three months ended June 30, 2018). Of the total expected proceeds, $54.6 million was received in March 2018 ($14.9 million of which were included in net cash flows from investing activities in discontinued operations). As of June 30, 2019, we have received a total of $70.4 million of the total expected proceeds, and have a remaining receivable from the buyer totaling approximately $14.8 primarily related to the working capital settlement. Additionally, Delek will be entitled to its pro rata portion of any tax credits relating to AltAir activities in 2018 earned through the sale date if the 2018 biodiesel tax credit is re-enacted. A receivable for such additional contingent proceeds will be recorded when the criteria for recognition are met, which is predicated upon reenactment of the tax credit and determination of the amounts earned by AltAir.

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 resulting in initial cash proceeds of approximately $14.5 million, net of expenses, and resulting in a gain on sale of discontinued operations of approximately $1.4 million during the third quarter of 2018.

The operating results, net of tax, from discontinued operations associated with the California Discontinued Entities are presented separately in Delek’s condensed consolidated statements of income and the notes to the condensed consolidated financial statements have been adjusted to exclude the discontinued operations. Components of amounts reflected in income (loss) from discontinued operations prior to their disposal are as follows (in millions):

	Three Months Ended			Six Months Ended

⁽¹⁾   Included in loss from discontinued operations is net income attributable to non-controlling interest totaling $8.1 million related to AltAir for the six months ended June 30, 2018 (none for the three months ended June 30, 2018).

Related to the California Discontinued Entities, all of which were disposed of by December 31, 2018, we retained certain obligations associated with various matters, including (but not necessarily limited to) California emissions credits requirements that were attributable to operations of the California Discontinued Entities for periods prior to disposition, litigations, claims or assessments related to matters/events that occurred prior to disposition, or indemnification of certain liabilities that related to the California Discontinued Entities and arose prior to

Notes to Condensed Consolidated Financial Statements (Unaudited)

disposition. Of these matters, we recorded related liabilities of $6.0 million and $5.0 million as of June 30, 2019 and December 31, 2018, respectively based on amounts that were deemed probable and could be reasonably estimated as of those dates. During the three and six months ended June 30, 2019, we recorded an additional accrual for California emission credit obligation based upon our revised estimates totaling $3.4 million. Additionally, in July 2019, we resolved a pending litigation matter (the Ten-Tex Litigation -- see Note 13) that resulted in a decrease in our accrual totaling $2.4 million during the three and six months ended June 30, 2019 (inclusive of the impact of our estimate of the liability for plaintiff legal fees). Such adjustments are included in loss from discontinued operations on the accompanying condensed consolidated statements of income for those periods.

Note 8 - Inventory

Crude oil, work in process, refined products, blendstocks and asphalt inventory for all of our operations, excluding the Tyler refinery and fuel inventory in our retail segment, are stated at the lower of cost determined using the first-in, first-out (“FIFO”) basis or net realizable value. Cost of all inventory at the Tyler refinery is determined using the last-in, first-out ("LIFO") inventory valuation method and inventory is stated at the lower of 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.

Carrying value of inventories consisted of the following (in millions):

	June 30, 2019		December 31, 2018
Refinery raw materials and supplies	$	413.7	$	289.0
Refinery work in process	85.0		58.9
Refinery finished goods	356.9		304.1
Retail fuel	7.1		8.0
Retail merchandise	24.2		25.4
Logistics refined products	4.7		5.5
Total inventories	$	891.6	$	690.9

At June 30, 2019, we recorded a pre-tax inventory valuation reserve of $2.5 million, $1.1 million of which related to LIFO inventory due to a market price decline below our cost of certain inventory products. At December 31, 2018, we recorded a pre-tax inventory valuation reserve of $54.0 million, $39.4 million of which related to LIFO inventory, which reversed in the first quarter of 2019 due to the sale of inventory quantities that gave rise to the December 31, 2018 reserve. We recognized a net (increase) reduction in cost of materials and other in the accompanying condensed consolidated statements of income related to the change in pre-tax inventory valuation of $(0.6) million and $51.5 million for the three and six months ended June 30, 2019, respectively, and $1.0 million and $1.9 million for the three and six months ended June 30, 2018, respectively.

Note 9 - Crude Oil Supply and Inventory Purchase Agreements

Delek has various Supply and Offtake Agreements (the "Supply and Offtake Agreements") with J. Aron & Company ("J. Aron").

El Dorado Supply and Offtake Agreement

The El Dorado refinery's Supply and Offtake Agreement as amended and restated on February 27, 2017 and in effect through December 2018 (the "El Dorado Supply and Offtake Agreement") provided for Lion Oil Company ("Lion Oil") (as the primary legal entity associated with the El Dorado refinery for purposes of this Agreement) and J. Aron to identify mutually acceptable contracts for the purchase of crude oil from third parties and J. Aron to supply up to 100,000 bpd of crude oil to the El Dorado refinery. Crude oil supplied to the El Dorado refinery by J. Aron is purchased daily at an estimated average monthly market price by Lion Oil. J. Aron will also purchase all refined products from the El Dorado refinery at an estimated daily market price, as they are produced. These daily purchases and sales are trued-up on a monthly basis in order to reflect actual average monthly prices. We have recorded a receivable related to this monthly settlement of $9.0 million and $7.8 million as of June 30, 2019 and December 31, 2018, respectively. Also pursuant to the El Dorado Supply and Offtake Agreement and other related agreements, Lion Oil arranges potential sales by either Lion Oil or J. Aron to third parties of the products produced at the El Dorado refinery or purchased from third parties. In instances where Lion Oil is the seller to such third parties, J. Aron will first transfer title of the applicable products to Lion Oil. The El Dorado Supply and Offtake Agreement has a maturity date of April 30, 2020. Based upon terms in effect as of December 31, 2018, upon the expiration or upon any earlier termination, Delek would be required to repurchase the consigned crude oil and refined products from J. Aron at then prevailing market prices.

22 |

Effective January 3, 2019, we amended the El Dorado Supply and Offtake Agreement with J. Aron that supports the operations of our El Dorado refinery so that the repurchase of baseline volumes at the end of the El Dorado Supply and Offtake Agreement term (representing the El Dorado "Baseline Step-Out Liability") will be based upon a fixed price instead of a market-indexed price. The modified arrangement results in a Baseline Step-Out Liability that is no longer subject to commodity volatility, but for which its fair value is now subject to interest rate risk. As a result, we recorded a gain on the change in fair value resulting from the modification of the instruments from commodities-based risk to interest rate risk in cost of materials and other totaling approximately $4.1 million in the first quarter of 2019, and we incurred $3.2 million in fees paid to J. Aron which were charged to interest expense. Such Baseline Step-Out Liability will continue to be recorded at fair value, where the fair value will reflect changes in interest rate risk rather than commodity price risk under the fair value election provided by ASC 815 Derivatives and Hedging ("ASC 815") and ASC 825, Financial Instruments ("ASC 825"). The change in fair value recorded during the three and six months ended June 30, 2019 related to the new instrument totaled $0.9 million and $(1.6) million, respectively, and is reflected as a increase (reduction) in interest expense.

At June 30, 2019 and December 31, 2018, Delek had 3.3 million barrels and 2.8 million barrels, respectively, of inventory consigned from J. Aron under the El Dorado Supply and Offtake Agreement, and we have recorded total liabilities associated with this consigned inventory of $178.8 million and $152.6 million, respectively, on the condensed consolidated balance sheets. As a result of the amendment to the El Dorado Supply and Offtake Agreement, as of June 30, 2019, the fair value of the Baseline Step-Out Liability totaling $104.5 million is reflected as a current obligation on our condensed consolidated balance sheet, and represents 2.0 million barrels of baseline consigned inventory. We maintained letters of credit with respect to the El Dorado Supply and Offtake Agreement totaling $150.0 million and $120.0 million at June 30, 2019 and December 31, 2018, respectively.

This arrangement is accounted for as a product financing. Delek incurred recurring fees payable to J. Aron under the El Dorado Supply and Offtake Agreement of $3.2 million and $5.7 million during the three and six months ended June 30, 2019, respectively, and $2.9 million and $5.6 million during the three and six months ended June 30, 2018, respectively. These amounts are included as a component of interest expense in the condensed consolidated statements of income. Upon any termination of the El Dorado Supply and Offtake Agreement, including in connection with a force majeure event, the parties are required 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.

Alon Supply and Offtake Agreements

Effective with the Delek/Alon Merger, we assumed Alon's existing Supply and Offtake Agreements and other associated agreements with J. Aron to support the operations of our Big Spring and Krotz Springs refineries and certain of our asphalt terminals (together, the “Alon Supply and Offtake Agreements”). Pursuant to the Alon Supply and Offtake Agreements, (i) J. Aron agreed to sell to us, and we agreed to buy from J. Aron, at market prices, crude oil for processing at these refineries and (ii) we agreed to sell, and J. Aron agreed to buy, at market prices, certain refined products produced at these refineries. The Alon Supply and Offtake Agreements also provide for the sale, at market prices, of our crude oil and certain refined product inventories to J. Aron, 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. The Alon Supply and Offtake Agreements have initial terms that expire in May 2021. J. Aron or Delek may elect to terminate the agreements at the Big Spring and Krotz Springs refineries in May 2020 on six months prior notice. The daily purchases and sales are trued-up on a monthly basis in order to reflect actual average monthly prices. We have recorded a net receivable (payable) related to this monthly settlement of $(10.6) million and $(1.0) million as of June 30, 2019 and December 31, 2018, respectively. Based upon terms in effect prior to the December 2018 and January 2019 amendments discussed below, upon the expiration or upon any earlier termination, Delek would be required to repurchase the consigned crude oil and refined products from J. Aron at then prevailing market prices.

Effective December 21, 2018, we amended our Supply and Offtake Agreement related to the Big Spring refinery (the "Big Spring Supply and Offtake Agreement") so that the repurchase of baseline volumes at the end of the Supply and Offtake Agreement term (representing the Big Spring "Baseline Step-Out Liability") will be based upon a fixed price instead of a market-indexed price. The modified arrangement results in a Baseline Step-Out Liability that is no longer subject to commodity volatility, but for which its fair value is now subject to interest rate risk. As a result for the Big Spring Supply and Offtake Agreement, we recorded a gain on the change in fair value resulting from the modification of the instruments from commodities-based risk to interest rate risk in cost of materials and other in the fourth quarter of 2018. Such Baseline Step-Out Liability will continue to be recorded at fair value, where the fair value will reflect changes in interest rate risk rather than commodity price risk under the fair value election provided by ASC 815 and ASC 825. Fees paid to J Aron as a result of this transaction were recorded as interest expense. As of June 30, 2019 and December 31, 2018 , the fair value of the Baseline Step-Out Liability for the Big Spring refinery was $48.3 million and $49.6 million, respectively, each based on 0.8 million barrels of baseline consigned inventory. As a result of the amendment, as of both June 30, 2019 and December 31, 2018, this baseline consigned inventory for the Big Spring refinery is reflected as a non-current obligation on our condensed consolidated balance sheet. The change in fair value recorded during the three and six months ended June 30, 2019 related to the new instrument totaled $0.2 million and $(1.3) million, respectively, and is reflected as a increase (reduction) in interest expense. There were no changes in our credit spread during the period that would require recognition in accumulated other comprehensive income pursuant to ASC 825.

At June 30, 2019 and December 31, 2018, Delek had 1.4 million barrels and 1.7 million barrels, respectively, of inventory consigned from J. Aron under the Big Spring Supply and Offtake Agreement, and we have recorded total liabilities associated with this consigned inventory of $77.4 million and $96.5 million, respectively, on the condensed consolidated balance sheets.

Effective January 2, 2019, we amended our Supply and Offtake Agreement related to the Krotz Springs refinery (the "Krotz Springs Supply and Offtake Agreement") so that the repurchase of baseline volumes at the end of the Supply and Offtake Agreement term (representing the Krotz Springs "Baseline Step-Out Liability") will also be based upon a fixed price instead of a market-indexed price. Like the Big Spring amendment, this modified arrangement results in a Baseline Step-Out Liability that is no longer subject to commodity volatility, but for which its fair value is now subject to interest rate risk. As a result for the Krotz Springs Supply and Offtake Agreement, we recorded a gain on the change in fair value resulting from the modification of the instruments from commodities-based risk to interest rate risk in cost of materials and other of $3.5 million in the first quarter of 2019, and we incurred $1.8 million in fees paid to J Aron which were charged to interest expense. Such Baseline Step-Out Liability will continue to be recorded at fair value, where the fair value will reflect changes in interest rate risk rather than commodity price risk under the fair value election provided by ASC 815 and ASC 825.

At June 30, 2019, Delek had 1.9 million barrels of inventory consigned from J. Aron under the Krotz Springs Supply and Offtake Agreement, inclusive of both the baseline volumes and over, short and excess target quantities, and we have total recorded liabilities associated with this consigned inventory of $124.3 million in the condensed consolidated balance sheets. As a result of the amendment, as of June 30, 2019, the fair value of the Baseline Step-Out Liability totaling $74.5 million for the Krotz Springs refinery is reflected as a non-current obligation on our condensed consolidated balance sheet, and represents 1.3 million barrels of baseline consigned inventory. The change in fair value recorded during the three and six months ended June 30, 2019 related to the new instrument totaled $0.3 million and $(0.8) million, respectively, and is reflected as a increase (reduction) in interest expense. There were no changes in our credit spread during the period that would require recognition in accumulated other comprehensive income pursuant to ASC 825.

Based upon terms in effect as of December 31, 2018 for the Krotz Springs Supply and Offtake Agreement, as of December 31, 2018, we had 1.8 million barrels of inventory consigned from J. Aron under the Krotz Springs Supply and Offtake Agreement, inclusive of both the baseline volumes and over, short and excess target quantities, and recorded a current liability associated with this consigned inventory of $113.1 million in the consolidated balance sheets, measured using the fair value election pursuant to ASC 825 (based on prevailing market-indexed pricing).

Both the Big Spring Supply and Offtake Agreement and the Krotz Springs Supply and Offtake Agreement are accounted for as product financing arrangements. Delek incurred recurring fees payable to J. Aron of $4.1 million and $7.9 million during the three and six months ended June 30, 2019, respectively, and $3.6 million and $6.9 million for the three and six months ended June 30, 2018, respectively. These amounts are included as a component of interest expense in the condensed consolidated statements of income. Upon any termination of the Alon Supply and Offtake Agreements, including in connection with a force majeure event, the parties are required 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.

We maintain letters of credit totaling $44.0 million and $24.0 million, as of June 30, 2019 and December 31, 2018, respectively with respect to the Alon Supply and Offtake Agreements. In connection with the Krotz Springs Supply and Offtake Agreement, we have granted a security interest to J. Aron in certain assets (including all of its accounts receivable and inventory) to secure our obligations to J. Aron.

Outstanding Obligations/Facilities as of the Balance Sheet Dates

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 $300.0 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.

In connection with the Refinancing, we recorded a loss on extinguishment of debt totaling approximately $9.0 million all of which was recorded in the first quarter of 2018.

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%, increasing the aggregate principal amount of loans outstanding under the Term Loan Credit Facility on the First Incremental Effective Date to $943.0 million. The terms of the Incremental Term 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 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 Amendment.

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 London Interbank Offered Rate ("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")). The initial applicable margin for all Term Loan Credit Facility borrowings was 1.50% per annum with respect to base rate borrowings and 2.50% per annum with respect to LIBOR borrowings.

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 borrowings under (i) Base Rate Loans from 1.50% to 1.25% and (ii) LIBOR Rate Loans from 2.50% to 2.25%, as such terms are defined in the Term Loan Credit Facility. 

The initial applicable margin for Revolving Credit Facility borrowings was 0.25% per annum with respect to base rate borrowings and 1.25% per annum with respect to LIBOR and CDOR borrowings, and the applicable margin for such borrowings after September 30, 2018 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, where the fee is at a rate of 0.25% or 0.375% per annum, depending on average commitment usage for such quarter. As of June 30, 2019, the unused line fee was 0.375% per annum.

Maturity and Repayments

The Revolving Credit Facility will mature and the commitments thereunder will terminate on March 30, 2023. Pursuant to Incremental Amendment, the Term Loan Credit Facility requires scheduled quarterly principal payments which increased from $1.750 million to $2.375 million commencing with the quarterly principal payment due on June 28, 2019, with the balance of the principal due on March 30, 2025.

Notes to Condensed Consolidated Financial Statements (Unaudited)

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 prepayments with a variable percentage of Delek’s excess cash flow, ranging from 50.0% to 0% depending on Delek’s consolidated secured net leverage ratio from time to time. Delek may also make voluntarily prepayments under the Term Loan Credit Facility at any time, subject to a prepayment premium of 1.0% in connection with certain customary repricing events that may occur within six months after the First Incremental Effective Date, with no premium applied after six months.

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 Partners, LP, 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, renewable identification numbers, 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 June 30, 2019, the weighted average borrowing rate under the Revolving Credit Facility was 5.75% and was comprised entirely of a base rate borrowing, and the principal amount outstanding thereunder was $75.0 million. Additionally, there were letters of credit issued of approximately $267.2 million as of June 30, 2019 under the Revolving Credit Facility. Unused credit commitments under the Revolving Credit Facility, as of June 30, 2019, were approximately $657.8 million.

At June 30, 2019, the weighted average borrowing rate under the Term Loan Credit Facility was approximately 4.58% comprised entirely of a LIBOR borrowing, and the principal amount outstanding thereunder was $940.6 million. As of June 30, 2019, the effective interest rate related to the Term Loan Credit Facility was 4.90%.

Delek Logistics Credit Facility

Prior to its amendment and restatement on September 28, 2018, Delek Logistics had a $700.0 million senior secured revolving credit agreement with Fifth Third Bank ("Fifth Third"), as administrative agent, and a syndicate of lenders (the "2014 Facility") with a $100.0 million accordion feature, bearing 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. 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 as administrative agent and a syndicate of lenders (hereafter, the "Delek Logistics Credit Facility"). Under the terms of the Delek Logistics Credit Facility, among other things, the lender commitments were increased from $700.0 million to $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. Additionally, a subsidiary of Delek continues to provide a limited guaranty of Delek Logistics' obligations under the Delek Logistics Credit Facility. The guaranty is (i) limited to an amount equal to the principal amount, plus unpaid and accrued interest, of a promissory note made by Delek in favor of the subsidiary guarantor (the "Holdings Note") and (ii) secured by the subsidiary guarantor's pledge of the Holdings Note to the Delek Logistics Credit Facility lenders. As of both June 30, 2019 and December 31, 2018, the principal amount of the Holdings Note was $102.0 million.

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 June 30, 2019, the weighted average borrowing rate was approximately 4.9%. 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 June 30, 2019, this fee was 0.40% per year.

As of June 30, 2019, Delek Logistics had $596.7 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 June 30, 2019, were $253.3 million.

Delek Logistics Notes

On May 23, 2017, Delek Logistics and Delek Logistics Finance Corp. (collectively, the “Issuers”) issued $250.0 million in aggregate principal amount of 6.75% senior notes due 2025 (the “Delek Logistics Notes”) at a discount. The Delek Logistics Notes are general unsecured senior obligations of the Issuers. The Delek Logistics Notes are unconditionally guaranteed jointly and severally on a senior unsecured basis by Delek Logistics' existing subsidiaries (other than Delek Logistics Finance Corp., the "Guarantors") and will be unconditionally guaranteed on the same basis by certain of Delek Logistics' future subsidiaries. The Delek Logistics Notes rank equal in right of payment with all existing and future senior indebtedness of the Issuers, and senior in right of payment to any future subordinated indebtedness of the Issuers. Interest on the Delek Logistics Notes is payable semi-annually in arrears on each May 15 and November 15, commencing November 15, 2017.

At any time prior to May 15, 2020, the Issuers may redeem up to 35% of the aggregate principal amount of the Delek Logistics Notes with the net cash proceeds of one or more equity offerings by Delek Logistics at a redemption price of 106.750% of the redeemed principal amount, plus accrued and unpaid interest, if any, subject to certain conditions and limitations. Prior to May 15, 2020, the Issuers may redeem all or part of the Delek Logistics Notes at a redemption price of the principal amount plus accrued and unpaid interest, if any, plus a "make whole" premium, subject to certain conditions and limitations. In addition, beginning on May 15, 2020, the Issuers may, subject to certain conditions and limitations, redeem all or part of the Delek Logistics Notes, at a redemption price of 105.063% of the redeemed principal for the twelve-month period beginning on May 15, 2020, 103.375% for the twelve-month period beginning on May 15, 2021, 101.688% for the twelve-month period beginning on May 15, 2022 and 100.00% beginning on May 15, 2023 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 Issuers will be obligated to make an offer for the purchase of the Delek Logistics Notes from holders at a price equal to 101.00% of the principal amount thereof, plus accrued and unpaid interest.

In May 2018, the Delek Logistics Notes were exchanged for new notes with terms substantially identical in all material respects with the 2025 Notes except the new notes do not contain terms with respect to transfer restrictions.

As of June 30, 2019, we had $250.0 million in outstanding principal amount under the Delek Logistics Notes. As of June 30, 2019, the effective interest rate related to the Delek Logistics Notes was 7.24%.

Reliant Bank Revolver

Delek has an unsecured revolving credit agreement with Reliant Bank (the "Reliant Bank Revolver") that provides for unsecured loans of up to $30.0 million. The Reliant Bank Revolver matures June 28, 2020, bears interest at fixed rate of 4.75% per annum and requires us to pay a quarterly fee of 0.50% per year on the average unused revolving commitment. As of June 30, 2019, we had $30.0 million outstanding and had no unused credit commitments under the Reliant Bank Revolver

Promissory Notes

On May 14, 2015, in connection with the Company’s closing of the acquisition of an equity method investment in Alon (the "Alon Acquisition"), the Company issued a promissory note (the "Alon Israel Note") in the amount of $145.0 million, which was payable to Alon Israel Oil Company, Ltd. ("Alon Israel"). The Alon Israel Note bears interest at a fixed rate of 5.50% per annum and requires five annual principal amortization payments of $25.0 million beginning in January 2016 followed by a final principal amortization payment of $20.0 million at maturity on January 4, 2021. In October 2015, we prepaid the first annual principal amortization payment in the amount of $25.0 million, along with all interest due on the prepaid amount. On December 22, 2015, Alon Israel assigned the remaining $120.0 million of principal and all accrued interest due under the Alon Israel Note to assignees under four new notes in substantially the same form and on the same terms as the Alon Israel Note (collectively, the "Alon Successor Notes"). The $120.0 million total principal of the four Alon Successor Notes collectively require the same principal amortization payments and schedule as under the Alon Israel Note, with payments due under each Alon Successor Note commensurate to such note's pro rata share of the $120.0 million in assigned principal. As of June 30, 2019, a total principal amount of $45.0 million was outstanding under the Alon Successor Notes.

Restrictive Covenants

Under the terms of our Revolving Credit Facility, Term Loan Credit Facility, Delek Logistics Credit Facility, Delek Logistics Notes and Reliant Bank Revolver, 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 June 30, 2019.

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. Specifically, these covenants may limit the payment, in the form of cash or other assets, of dividends or other distributions, or the repurchase of shares with respect to the equity of the Company or certain of our subsidiaries. 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.

Instruments Outstanding as of June 30, 2018

Alon Convertible Senior Notes

In connection with the Delek/Alon Merger, Alon, New Delek and U.S. Bank National Association, as trustee (the “Trustee”) entered into a First Supplemental Indenture (the “Supplemental Indenture”), effective as of July 1, 2017, which provided that Alon's 3.00% Convertible Senior Notes due September 2018, which were previously convertible into Alon Common Stock, to thereafter be convertible into New Delek Common Stock based on the exchange rate applied in the Delek/Alon Merger (as previously defined, the “Convertible Notes”). Additionally, In connection with the Convertible Notes, Alon also entered into equity instruments, including call options (as previously defined, the "Call Options") and warrants (as previously defined, the "Warrants"), designed, in combination, to hedge a portion of the economic risk associated with the potential exercise of the conversion feature of the Convertible Notes and to mitigate the dilutive effect of such potential conversion. The aggregate principal amount of the Convertible Notes was $150.0 million, and the effective interest rate as of June 30, 2018 was 5.92%, resulting in recognition of total interest expense during the three and six months then ended of approximately $2.2 million and $4.4 million, respectively.

The Convertible Notes could be converted into shares of Delek Common Stock, into cash, or into a combination of cash and shares of New Delek Common Stock, at our election. In May 2018, we made the election and notified holders of our intention to satisfy the principal amount outstanding with cash and the incremental value of the conversion options with shares at maturity. The conversion rate of the Convertible Notes was subject to adjustment upon the occurrence of certain events, including cash dividend adjustments. On September 17, 2018, Delek settled the Convertible Notes for a combination of cash and shares of New Delek Common Stock. The maturity settlement in respect of the Convertible Notes consisted of (i) cash payments totaling approximately $152.5 million which included a cash payment for outstanding principal of $150.0 million, a cash payment for accrued interest of approximately $2.2 million, a cash payment for dividends of approximately $0.3 million and a nominal cash payment in lieu of fractional shares, and (ii) the issuance of approximately 2.7 million shares of New Delek Common Stock to holders of the Convertible Notes (the “Conversion Shares”). The issuance of the Conversion Shares was made in exchange for the

28 |

Notes to Condensed Consolidated Financial Statements (Unaudited)

Convertible Notes pursuant to an exemption from the registration requirements provided by Section 3(a)(9) of the Securities Act of 1933, as amended.

Prior to the conversion, the conversion feature met the definition for recognition as a bifurcated equity instrument. At June 30, 2018, the conversion feature equity instrument totaled $26.6 million and was included in additional paid-in capital on the accompanying condensed consolidated balance sheets.

Convertible Note Hedge Transactions

In connection with the Convertible Notes offering, Alon entered into convertible note hedge transactions with respect to Alon Common Stock (as previously defined, the “Call Options”) with the initial purchasers of the Convertible Notes (the “Hedge Counterparties”). In connection with the Delek/Alon Merger, Alon, Delek and the Hedge Counterparties entered into amended and restated Call Options permitting us to purchase up to approximately 5.7 million shares of New Delek Common Stock, subject to customary anti-dilution adjustments, that underlie the Convertible Notes sold in the offering.

On September 17, 2018, we exercised the Call Options in connection with the settlement of the Convertible Notes and received approximately 2.7 million shares of our common stock from the Call Option counterparties, a cash payment for dividends of approximately $0.3 million and a nominal cash payment in lieu of fractional shares. On a net basis, the settlement of the Convertible Notes and the exercise of the Call Options resulted in no net dilution to our common stock. Prior to their exercise, the Call Options totaling $23.3 million were included as a reduction of additional paid-in capital on the condensed consolidated balance sheets.

Warrant Transactions

In connection with the Convertible Notes offering, Alon also entered into warrant transactions (as previously defined, the “Warrants”) whereby warrants to acquire Alon common stock were sold to the Hedge Counterparties. In connection with the Delek/Alon Merger, Alon, Delek and the Hedge Counterparties entered into amended and restated Warrants which allow the Hedge Counterparties to purchase up to approximately 5.7 million shares of New Delek Common Stock, subject to customary anti-dilution adjustments. In November 2018, Delek entered into Warrant Unwind Agreements (as previously defined, the "Unwind Agreements") with the holders of our outstanding common stock Warrants. Pursuant to the terms of the Unwind Agreements, we settled for cash all outstanding Warrants with the holders at various prices per Warrant as provided in the Unwind Agreements. The settlement amount was based on the volume-weighted average market price of our common stock taking into account an adjustment for the exercise price of the Warrants over a period of sixteen trading days beginning November 9, 2018 (the “Unwind Period”). Following the Unwind Period and upon the satisfaction of the payment obligation, the Warrants were canceled and the associated rights and obligations terminated. Based on the provisions of the Unwind Agreements, the amount paid to warrant holders in satisfaction of the payment obligation totaled approximately $36.0 million.

Obligations Extinguished in Connection with the March 2018 Refinancing

Prior to the Refinancing, Delek had outstanding various credit facilities/debt instruments as follows:

Wells ABL

Our subsidiary, Delek Refining, Ltd., had an asset-based loan credit facility with Wells Fargo Bank, National Association, as administrative agent, and a syndicate of lenders, which was previously amended and restated on September 29, 2016 and on May 17, 2017 (the "Wells ABL"). This facility was amended and restated on March 30, 2018 in connection with the Refinancing. The Wells ABL consisted of (i) a $450.0 million revolving loan (the "Wells Revolving Loan") and (ii) a $70 million term loan ("Wells Term Loan"). Borrowings under the Wells Revolving Loan and Wells Term Loan bore interest based on separate predetermined pricing grids that allowed us to choose between base rate loans or LIBOR rate loans. Additionally, the Wells ABL required us to pay a quarterly unused credit commitment fee.

Lion Term Loan

Our subsidiary, Lion Oil, had a term loan credit facility with Fifth Third Bank, as administrative agent, and a syndicate of lenders, which, as amended and restated, had a total loan size of $275.0 million (the "Lion Term Loan"). This facility was extinguished in connection with the Refinancing on March 30, 2018. Interest on the unpaid balance of the Lion Term Loan was computed at a rate per annum equal to LIBOR or a base rate, at our election, plus the applicable margins, subject in each case to an all-in interest rate floor of 5.50% per annum.

Alon Partnership

Revolving Credit Facility

Alon USA, LP, a wholly-owned subsidiary of the Alon Partnership had a $240.0 million asset-based revolving credit facility with Israel Discount Bank of New York, as administrative agent (the “Alon Partnership Credit Facility”). This facility was extinguished in connection with the Refinancing on March 30, 2018. Borrowings under the Alon Partnership Credit Facility bore interest at LIBOR or base rate, at our election, plus the applicable margins.

Partnership Term Loan Credit Facility

The Alon Partnership had a $250.0 million term loan with Credit Suisse AG, as administrative agent (the “Alon Partnership Term Loan”). This term loan was extinguished in connection with the Refinancing on March 30, 2018. The Alon Partnership Term Loan bore interest at a rate per annum equal to LIBOR (subject to a floor of 1.25%) or a base rate plus the applicable margins.

Alon Term Loan Credit Facilities

Alon Energy Term Loan

Alon had a promissory note to Bank Hapoalim B.M. in an original principal amount of $38.0 million ("New Alon Energy Term Loan"). The New Alon Energy Term Loan was extinguished in connection with the Refinancing on March 30, 2018. The New Alon Energy Term Loan incurred interest at an annual rate equal to LIBOR plus an applicable margin.

Alon Asphalt Term Loan

Alon had a term loan owed to Export Development Canada secured by liens on certain of our asphalt terminals (“Alon Asphalt Term Loan”) in an original principal amount of $35.0 million. This loan was prepaid on March 29, 2018 in connection with the Refinancing on March 30, 2018. The Alon Asphalt Term Loan bore interest at a rate equal to LIBOR plus an applicable margin.

Alon Retail Credit Agreement

Alon wholly-owned subsidiaries Southwest Convenience Stores, LLC and Skinny’s LLC, (collectively, “Alon Retail”), had a credit agreement (“Alon Retail Credit Agreement”), that was to mature in March 2019, with Wells Fargo Bank, National Association, as administrative agent. This credit agreement was extinguished in connection with the Refinancing on March 30, 2018. The Alon Retail Credit Agreement included a term loan in an original principal amount of $110.0 million and a $10.0 million revolving credit facility. Borrowings under the Alon Retail Credit Agreement bore interest at LIBOR or base rate, at our election, plus an applicable margin, determined quarterly based upon Alon Retail’s leverage ratio.

Interest-Rate Derivative Instruments

Effective with the Delek/Alon Merger, we assumed Alon's interest rate swap agreements that were to mature in March 2019, which effectively fixed the variable LIBOR interest component of the term loans within the Alon Retail Credit Agreement. These interest rate swap agreements were terminated in connection with the Refinancing on March 30, 2018. These interest rate swaps were accounted for as cash flow hedges. See Note 11 for further information regarding the interest rate swap agreements.

Note 11 - 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 the exposure to price fluctuations of commodity inventory above or below target levels at each of our segments;

• managing our exposure to commodity price risk associated with the purchase or sale of crude oil, feedstocks and finished grade fuel products at each of our segments;

• managing the cost of our credits for commitments required by the U.S. Environmental Protection Agency ("EPA") to blend biofuels into fuel products ("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 borrowings.

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 swap agreements, to achieve these objectives. Futures contracts are standardized agreements, traded on a futures exchange, to buy or sell the commodity at a predetermined price at a specified future date. Options provide the right, but not the obligation to buy or sell the commodity at a specified price in the future. Commodity swap 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 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.

During the first quarter of 2018, we utilized interest rate swap agreements to hedge floating rate debt by exchanging interest rate cash flows, based on a notional amount from a floating rate to a fixed rate. Effective with the Delek/Alon Merger, we had four interest rate swap agreements (that had maturities in March 2019) which effectively fixed the variable LIBOR interest component of the term loan within the Alon Retail Credit Agreement. The aggregate notional amount under these agreements were to cover approximately 77% of the outstanding principal of these term loans throughout the duration of the interest rate swaps. These interest rate swap agreements were terminated due to the extinguishment of the Alon Retail Credit Agreement in connection with the Refinancing on March 30, 2018, resulting in a reclassification of unrealized loss of $0.6 million from accumulated other comprehensive income to interest expense on the condensed consolidated statements of income during the three months ended March 31, 2018.

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 normal purchases and normal sales pursuant to ASC 815 and are not accounted for as derivative instruments. Rather, such forward contracts are accounted for under other applicable GAAP. Forward contracts entered into for trading purposes that do not meet the normal purchases, normal sales exception are accounted for as derivative instruments at fair value with changes in fair value recognized in earnings in the period of change. As of and for the three and six months ended June 30, 2019 and the year ended December 31, 2018, all of our forward contracts that were accounted for as derivative instruments consisted of contracts related to our Canadian crude trading operations. Since Canadian crude trading activity is not related to managing supply or pricing risk of inventory that will be used in production, such unrealized and realized gains and losses are recognized in other operating income, net rather than cost of materials and other on the accompanying condensed consolidated statements of income.

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 RIN 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 RIN commitment contracts are recorded in cost of materials and other on the condensed 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.

Notes to Condensed Consolidated Financial Statements (Unaudited)

In accordance with ASC 815, certain of our commodity swap contracts and our interest rate agreements have been designated as cash flow hedges and the change in fair value between the execution date and the end of period (or early termination date in regards to the four Alon retail interest rate swaps discussed above) has been recorded in other comprehensive income. The fair value of these contracts is recognized in income 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 June 30, 2019 and December 31, 2018. 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 condensed consolidated balance sheets. See Note 12 for further information regarding the fair value of derivative instruments (in millions):

Note 12 - Fair Value Measurements

Delek applies the provisions of ASC 820, Fair Value Measurements ("ASC 820"), which defines fair value, establishes a framework for its measurement and expands disclosures about fair value measurements. ASC 820 requires disclosures that categorize 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.

Commodity swaps, exchange-traded futures, options, physical commodity forward purchase and sale contracts (that do not qualify as normal purchases or normal sales), and interest rate swaps are generally valued using industry-standard models that consider various assumptions, including quoted forward prices, spot prices, interest rates, time value, volatility factors and contractual prices for the underlying instruments, as well as other relevant economic measures. The degree to which these inputs are observable in the forward markets determines the classification as Level 2 or 3. Our contracts are valued based on exchange pricing and/or price index developers such as Platts or Argus and are, therefore, classified as Level 2. Commodity investments are valued using published market prices of the commodity on the applicable exchange and are, therefore, classified as Level 1.

Our Environmental Credits Obligation surplus or deficit is based on the amount of RINs or other emissions credits we must purchase, net of amounts internally generated and purchased and the price of those RINs or other emissions credits as of the balance sheet date, by refinery/obligor. The Environmental Credits Obligation surplus or deficit is categorized as Level 2, and is measured at fair value either directly through observable inputs or indirectly through market-corroborated inputs.

In March 2018, the El Dorado refinery received approval from the EPA for a small refinery exemption from the requirements of the renewable fuel standard for the 2017 calendar year, which resulted in a reduction of our RINs Obligation and related cost of materials and other of approximately $59.3 million for the six months ended June 30, 2018. In March 2018, the Krotz Springs refinery received such approval for 2017 as well, which resulted in a reduction of our RINs Obligation and related cost of materials and other of approximately $31.6 million for the six months ended June 30, 2018.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Our RIN 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 RINs Obligation. These RIN commitment contracts are categorized as Level 2, and are measured at fair value based on quoted prices from an independent pricing service. Changes in the fair value of these future RIN commitment contracts are recorded in cost of materials and other on the condensed consolidated statements of income.

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. As of and for the six months ended June 30, 2019 and 2018, 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. Our J. Aron step-out liability was categorized as Level 2, and measured at fair value using market prices for the consigned crude oil and refined products we were required to repurchase from J. Aron at the end of the term of the Supply and Offtake Agreement prior to the December 2018/January 2019 amendments to each of the Supply and Offtake Agreements. The J. Aron step-out liability was presented in the Obligation under Supply and Offtake Agreement line item of our condensed consolidated balance sheets. Gains (losses) related to the change in fair value was recorded as a component of cost of materials and other in the condensed consolidated statements of income. With respect to the amended Supply and Offtake Agreements, such amendments being effective December 2018 for our Big Spring Agreement and January 2019 for our El Dorado and Krotz Springs Agreements, we apply fair value measurement as follows: (1) we determine fair value for our amended fixed-price step-out liability based on changes in fair value related to interest rate risk where such obligation is categorized as Level 2 and is presented in the current or long-term portion, based on maturity of the agreement, of the Obligation under Supply and Offtake Agreements on our condensed consolidated balance sheets, and where gains (losses) related to changes in fair value are recorded as a component of interest expense in the condensed consolidated statements of income; and (2) we determine fair value of the short-term commodity-indexed financing facility 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 condensed consolidated balance sheets, and where gains (losses) related to the change in fair value are recorded as a component of cost of materials and other in the condensed consolidated statements of income.

Commodity investments represent those commodities (generally crude oil) physically on hand as a result of trading activities with physical forward contracts. Such investment stores are maintained on a weighted average cost basis for determining realized gains and losses on physical sales under forward contracts, and ending balances are adjusted to fair value at each reporting date. The unrealized loss on commodity investments for the three and six months ended June 30, 2019 totaled $1.0 million and $2.0 million, respectively.

The fair value hierarchy for our financial assets and liabilities accounted for at fair value on a recurring basis was as follows (in millions):

The derivative values above are based on analysis of each contract as the fundamental unit of account as required by ASC 820. 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 June 30, 2019 and December 31, 2018, $0.5 million and $0.4 million, respectively, of cash obligation 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.

Note 13 - 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 2014, 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 is included as of June 30, 2019 in accrued expenses and other current liabilities on the accompanying condensed consolidated balance sheet, and which reflects a $5.7 million increase in the accrual recorded during the three months ended June 30, 2019. Additionally, through June 30, 2019, we have incurred $1.2 million of related legal expenses, $1.0 million and $1.1 million of which was incurred during the three and six months ended June 30, 2019, respectively, and has been recorded in general and administrative expenses in the accompanying condensed consolidated statements of income.

As of June 30, 2019 and December 31, 2018, AltAir (one of the California Discontinued Entities) was the party to a lawsuit whereby the plaintiff alleged breach of contract relating to a supply agreement during the period prior to the Delek/Alon Merger. We recorded a contingent liability associated with this matter (the "Ten-Tex Litigation") totaling $5.0 million as part of the purchase price allocation, which was finalized in June 2018. In July 2019, we reached a settlement with the plaintiff, whereby we are obligated for $2.3 million of the judgment against AltAir. Additionally, we believe that it's probable that the plaintiff will be successful in recovering a portion of its legal fees, and have estimated this liability to be approximately $0.3 million. Because the settlement was reached prior to the issuance of these consolidated financial statements, we have reduced our litigation accrual by $2.4 million during the three and six months ended June 30, 2019, which has been recorded in loss from discontinued operations (See Note 7).

Self-insurance

Delek records a self-insurance accrual for workers’ compensation claims up to a $1.0 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 $1.0 million deductible on a per accident basis for claims incurred in recent periods, and up to a $4.0 million deductible for remaining claims from certain prior periods.

Notes to Condensed Consolidated Financial Statements (Unaudited)

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, the Occupational Safety and Health Administration, 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.

The Big Spring refinery has been negotiating an agreement with the EPA for over 10 years under the EPA’s National Petroleum Refinery Initiative regarding alleged historical violations of the federal Clean Air Act related to emissions and emissions control equipment. A Consent Decree resolving these alleged historical violations for the Big Spring refinery was lodged with the United States District Court for the Northern District of Texas on June 6, 2017. An amendment to the Consent Decree was agreed upon by Delek and the EPA/ United States Department of Justice (the "DOJ"), in late 2018 and was executed by Delek. The amended Consent Decree was lodged during the first quarter of 2019, and was entered by the Court on June 5, 2019. The civil penalty of $0.5 million was paid on June 18, 2019. Per the Consent Decree, the Company will be required to expend capital for pollution control equipment that may be significant over the next 10 years.

As of June 30, 2019, we have recorded an environmental liability of approximately $142.3 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, which were already being performed by the former operators of the refineries and terminals prior to our acquisition of those facilities, for known contamination of soil and groundwater, as well as estimated costs for additional issues which have been identified subsequent to the acquisitions. Approximately $3.7 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.

Crude Oil Releases

We have experienced several crude oil releases involving our assets, including four releases that occurred in the first quarter of 2019, three releases that occurred in the first quarter of 2018, and three releases that occurred in the fourth quarter of 2018. Cleanup operations and site maintenance and remediation efforts on these and other releases have been substantially completed. Confirmatory sampling is currently underway. We expect regulatory closure by the end of 2019. There were no significant spills in the second quarter of 2019.

Many of the releases have occurred on the SALA Gathering System. Currently, we are in the process of decommissioning certain sections of the SALA Gathering System in an effort to improve the safety and integrity of the system. We do not expect for the decommissioning of certain gathering lines on the system to have a material effect on the operational capabilities of the system.

The DOJ, on behalf of the EPA, and the State of Arkansas, on behalf of the Arkansas Department of Environmental Quality, have been pursuing an enforcement action against Delek Logistics with regard to potential violations of the Clean Water Act and certain state laws arising from the release of crude oil from a pumping facility at its Magnolia Station near the El Dorado Refinery ( the "Magnolia Release") since June 2015. On July 13, 2018, the DOJ and the State of Arkansas filed a civil action against two of Delek Logistics’ wholly-owned subsidiaries, Delek Logistics Operating LLC and SALA Gathering Systems LLC, in the United States District Court for the Western District of Arkansas.

In December 2018, Delek, the Unites States and the state of Arkansas reached an agreement to settle the claims related to the Magnolia Release for $2.2 million and the claims against Delek Logistics were resolved and an additional demand for a compliance audit at the Magnolia terminal was abandoned pursuant to payment of monetary penalties and other relief. As of June 30, 2019, we have accrued $2.2 million for the Magnolia Release. We believe this amount is adequate to cover our expected obligations related to these proceedings. The accrual is recorded in accrued expenses and other current liabilities in our condensed consolidated balance sheet. In July 2019, Delek signed and

Notes to Condensed Consolidated Financial Statements (Unaudited)

submitted to the DOJ, a consent decree (the "Magnolia Consent Decree") to settle the release.  We expect the Magnolia Consent Decree to be finalized and to settle the accrual in the second half of 2019.

Letters of Credit

As of June 30, 2019, we had in place letters of credit totaling approximately $267.2 million with various financial institutions securing obligations primarily with respect to our commodity purchases for the refining segment and certain of our insurance programs. There were no amounts drawn by beneficiaries of these letters of credit at June 30, 2019.

Note 14 - Income Taxes

Under ASC 740, Income Taxes (“ASC 740”), companies are required to apply an estimated annual tax rate to interim period results on a year-to-date basis; however, the estimated annual tax rate should not be applied to interim financial results if a reliable estimate cannot be made.  In this situation, the interim tax rate should be based on actual year-to-date results.  We used an estimated annual tax rate to record income taxes for the three and six months ended June 30, 2019 and June 30, 2018.

For the three and six months ended June 30, 2018, we recorded additional income tax expense of $10.0 million and $2.6 million, respectively as a component of income tax expense from continuing operations related to the continued assessment of the tax effects of the 2017 Tax Cuts and Jobs Act ("Tax Reform Act"). This adjustment to the previously recorded provisional amounts include the tax effects on the remeasurement of the existing net deferred tax liabilities. We also had a reclassification of $1.6 million from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Reform Act, which was recorded during the first quarter of 2018.

Our effective tax rate was 22.5% and 22.8% for the three and six months ended June 30, 2019, respectively, compared to 27.3% and 23.3% for the three and six months ended June 30, 2018, respectively. The change in our effective tax rate was primarily due to the following discrete adjustments that were reported in the first and second quarters of 2018: further remeasurement of deferred tax assets and liabilities to properly account for the effects of the Tax Reform Act under Staff Accounting Bulletin 118; tax benefit for federal tax credits attributable to the Company's biodiesel blending operations for 2017 that have not been extended by Congress; tax expense associated with the impairment of assets held for sale; and changes in valuation allowance attributable to the book-tax basis differences from the Big Spring Logistic Asset Acquisition (See Note 5).

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 three and six months ended June 30, 2019, 1,647,078 and 2,938,722 shares of our common stock were repurchased for a total of $58.6 million and $104.8 million, respectively, compared to repurchases of 371,271 and 2,941,203 shares during the three and six months ended June 30, 2018 for a total of $20.0 million and $115.3 million, respectively.

The service cost component of net periodic benefit is included as part of general and administrative expenses in the accompanying condensed consolidated statements of income. The other components of net periodic benefit are included as part of other non-operating expense (income), net in the accompanying condensed consolidated statements of income. During the year ended December 31, 2018, we completely settled the supplemental retirement income plan of the retail segment, and we had a partial settlement of Alon's executive non-qualified restoration plan. In addition, we entered into an agreement with the International Union of Operating Engineers (the "Union") to extend the Union agreement to March 31, 2022, and to freeze Alon's qualified pension plan for union employees effective July 31, 2018. 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, where payments are contingent upon continued employment at each annual payment date. The payments, the first of which was made in July 2018, are expected to total approximately $6.9 million in the aggregate without considering forfeitures (which cannot yet be estimated). The related expense has been or will be recognized over the remaining union contract period as follows (estimated without considering forfeitures): approximately $1.0 million during the six months ended June 30, 2019 and approximately $1.0 million for the remainder of 2019; approximately $2.0 million during each of the years 2020 and 2021, and approximately $0.1 million in 2022. In addition during the fourth quarter of 2018, we spun off a portion of the Alon's qualified pension plan into a new plan for Union employees - The Alon USA Pension Plan for Collective Bargained 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 the projected benefit obligation (the "Projected Benefit Obligation") which is the present value of benefits earned to date by plan participants, including the effect of assumed future salary increases.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Our estimated contributions to our pension plans during 2019 have not changed significantly from amounts previously disclosed in the notes to the consolidated financial statements for the year ended December 31, 2018. For the three and six months ended June 30, 2019, we made no contributions to our funded qualified pension plan and made contributions of $0.1 million related to payments to participants in our unfunded pension plans for the six months ended June 30, 2019, none of which were made in the second quarter of 2019.

Note 20. Leases

We lease certain retail stores, land, building and various equipment. 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 to 15 years or more. The exercise of existing lease renewal options is at our sole discretion. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

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 stores and crude storage equipment.

As of June 30, 2019, $30.0 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.

On July 29, 2019, our Board of Directors voted to declare a quarterly cash dividend of $0.29 per share of our common stock, payable on September 3, 2019 to shareholders of record on August 19, 2019.

Settlement of Litigation

In July 2019, we reached a settlement on the Ten-Tex Litigation (see Note 13) related to one of the California Discontinued Entities that resulted in a reduction in our contingent loss accrual totaling $2.4 million, resulting in a remaining obligation (inclusive of an estimate for our obligation for plaintiff legal fees) of $2.6 million. Such reduction has been recorded in loss from discontinued operations on the accompanying consolidated statements of operations for the three and six months ended June 30, 2019. See Notes 7 and 13 for further discussion.

Investment in Pipeline Joint Venture

On July 30, 2019, we, through our wholly-owned direct subsidiary Delek US Energy, Inc. (“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 will have a 15% ownership interest in WWP. 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) and it is anticipated that Delek Energy’s capital contributions will total approximately $340 million to $380 million over the course of construction (expected to be two to three years), with an initial capital contribution of $40.0 million due within 30 days of the execution of the LLCA.

Management's Discussion and Analysis

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is management’s analysis of our financial performance and of significant trends that may affect our future performance. The MD&A should be read in conjunction with our condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q and in the Annual Report on Form 10-K as amended and filed with the Securities and Exchange Commission ("SEC") on June 27, 2019 (the "Annual Report on Form 10-K"). Those statements in the MD&A that are not historical in nature should be deemed forward-looking statements that are inherently uncertain.

In January 2017, Delek US Holdings, Inc. ("Old Delek") (and various related entities) entered into an Agreement and Plan of Merger with Alon USA Energy, Inc. (NYSE: ALJ) ("Alon") (as amended, the "Merger Agreement"). The related merger (the "Delek/Alon Merger") was effective July 1, 2017 (the “Effective Time”), resulting in a new post-combination consolidated registrant renamed Delek US Holdings, Inc. (“New Delek”), with Alon and Old Delek surviving as wholly-owned subsidiaries. New Delek is the successor issuer to Old Delek and Alon USA pursuant to Rule 12g-3(c) under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Unless otherwise noted or the context requires otherwise, the terms "we," "our," "us," "Delek" and the "Company" are used in this report to refer to Old Delek and its consolidated subsidiaries for the periods prior to July 1, 2017, and New Delek and its consolidated subsidiaries for the periods on or after July 1, 2017 - see Note 1 of the condensed consolidated financial statements in Item 1, Financial Statements, for additional information.

You should read the following discussion of our financial condition and results of operations in conjunction with our historical condensed consolidated financial statements and notes thereto.

Forward-Looking Statements

This Quarterly Report on Form 10-Q contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. These forward-looking statements reflect our current estimates, expectations and projections about our future results, performance, prospects and opportunities. Forward-looking statements include, among other things, the information concerning our possible future results of operations, business and growth strategies, financing plans, expectations that regulatory developments or other matters will or will not have a material adverse effect on our business or financial condition, our competitive position and the effects of competition, the projected growth of the industry in which we operate, and the benefits and synergies to be obtained from our completed and any future acquisitions, statements of management’s goals and objectives, and other similar expressions concerning matters that are not historical facts. Words such as "may," "will," "should," "could," "would," "predicts," "potential," "continue," "expects," "anticipates," "future," "intends," "plans," "believes," "estimates," "appears," "projects" and similar expressions, as well as statements in future tense, identify forward-looking statements.

Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking information is based on information available at the time and/or management’s good faith belief with respect to future events, and is subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in the statements. Important factors that, individually or in the aggregate, could cause such differences include, but are not limited to:

• volatility in our refining margins or fuel gross profit as a result of changes in the prices of crude oil, other feedstocks and refined petroleum products;

• reliability of our operating assets;

• actions of our competitors and customers;

• changes in, or the failure to comply with, the extensive government regulations applicable to our industry segments;

• our ability to execute our strategy of growth through acquisitions and capital projects and changes in the expected value of and benefits derived therefrom, including any ability to successfully integrate acquisitions, realize expected synergies or achieve operational efficiency and effectiveness;

• diminishment in value of long-lived assets may result in an impairment in the carrying value of the assets on our balance sheet and a resultant loss recognized in the statement of operations;

• general economic and business conditions affecting the southern, southwestern and western United States, particularly levels of spending related to travel and tourism;

• volatility under our derivative instruments;

• deterioration of creditworthiness or overall financial condition of a material counterparty (or counterparties);

• unanticipated increases in cost or scope of, or significant delays in the completion of, our capital improvement and periodic turnaround projects;

• risks and uncertainties with respect to the quantities and costs of refined petroleum products supplied to our pipelines and/or held in our terminals;

• operating hazards, natural disasters, casualty losses and other matters beyond our control;

• increases in our debt levels or costs;

42 |

Management's Discussion and Analysis

• changes in our ability to continue to access the credit markets;

• compliance, or failure to comply, with restrictive and financial covenants in our various debt agreements;

• the inability of our subsidiaries to freely make dividends, loans or other cash distributions to us;

• seasonality;

Executive Summary and Strategic Overview

Business Overview

We are an integrated downstream energy business focused on petroleum refining, the transportation, storage and wholesale distribution of crude oil, intermediate and refined products and convenience store retailing. Effective July 1, 2017, we acquired through the Delek/Alon Merger the operations and net assets of Alon. The Delek/Alon Merger continues to have a significant impact on our revenue and profitability as well as earnings per share, our net asset position, our purchasing position in the marketplace, our footprint in the refining industry, especially in the Gulf Coast Region/Permian Basin, and our ability to go to market and secure financing.

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 bpd, including the 75,000 bpd Tyler, Texas refinery (the "Tyler refinery"), the 80,000 bpd El Dorado, Arkansas refinery (the "El Dorado refinery"), the 73,000 bpd Big Spring, Texas refinery (the "Big Spring refinery"), and the 74,000 bpd Krotz Springs, Louisiana refinery (the "Krotz Springs refinery"), as well as a non-operating refinery located in Bakersfield, California. The refining segment also owns and operates two biodiesel facilities involved in the production of biodiesel fuels and related activities, located in Crossett, Arkansas and Cleburn, Texas. The refining segment's petroleum-based products are marketed primarily in the south central, southwestern and western regions of the United States, and the refining 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, we sell motor fuels through our wholesale distribution network on an unbranded basis.

Our profitability in the refining segment is substantially determined by the difference between the cost of the crude oil feedstocks we purchase and the price of the refined products we sell, referred to as the "crack spread", "refining margin" or "refined product margin". Refining margin is used as a metric to assess a refinery's product margins against market crack spread trends, where "crack spread" is a measure of the difference between market prices for crude oil and refined products and is a commonly used proxy within the industry to estimate or identify trends in refining margins. The cost to acquire feedstocks and the price of the refined petroleum products we ultimately sell from our refineries depend on numerous factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined petroleum products which, in turn, depend on, among other factors, changes in domestic and foreign economies, weather conditions such as hurricanes or tornadoes, local, domestic and foreign political affairs, global conflict, production levels, the availability of imports, the marketing of competitive fuels and government regulation. Other significant factors that influence our results in the refining segment include operating costs (particularly the cost of natural gas used for fuel and the cost of electricity), seasonal factors, refinery utilization rates and planned or unplanned maintenance activities or turnarounds. Demand for gasoline and asphalt products is generally higher during the summer months than during the winter months due to seasonal increases in motor vehicle traffic and road and home construction. Varying vapor pressure requirements between the summer and winter months also tighten summer gasoline supply. As a result, our operating results are generally lower for the first and fourth quarters of the calendar year. Moreover, while the fluctuations in the cost of crude oil are typically reflected in the prices of light refined products, such as gasoline and diesel fuel, the price of other residual products, such as asphalt, coke, carbon black oil and liquefied petroleum gas ("LPG"), are less likely to move in parallel with crude cost. This could cause additional pressure on our realized margin during periods of rising or falling crude oil prices. Additionally, our margins are impacted by the pricing differentials of the various types and sources of crude

Management's Discussion and Analysis

oil we use at our refineries and their relation to product pricing, such as the differentials between West Texas Intermediate ("WTI") Midland and WTI Cushing or WTI Midland and Brent crude oil.

With respect to measuring our refining margins at our refineries, we consider the following:

• For our Tyler refinery, we compare our per barrel refined product margin to the U.S.Gulf Coast ("Gulf Coast") 5-3-2 crack spread. The Gulf Coast 5-3-2 crack spread is used as a benchmark for measuring a refinery's product margins by measuring the difference between the market price of light products and crude oil, and represents the approximate refining margin resulting from processing one barrel of crude oil into three-fifths barrel of gasoline and two-fifths barrel of high-sulfur diesel.

• For our Big Spring refinery, we compare our per barrel refined product margin to the Gulf Coast 3-2-1 crack spread. The Gulf Coast 3-2-1 crack spread is calculated assuming that one barrel of WTI Cushing crude oil are converted into two-thirds barrel of Gulf Coast conventional gasoline and one-third barrel of Gulf Coast ultra-low sulfur diesel. Our Big Spring refinery is capable of processing substantial volumes of sour crude oil, which has historically cost less than intermediate, and/or substantial volumes of sweet crude oils, and therefore the WTI Cushing/WTS price differential, taking into account differences in production yield, is an important measure for helping us make strategic, market-respondent production decisions.

• For our Krotz Springs refinery, we compare our per barrel refined product margin to the Gulf Coast 2-1-1 high sulfur diesel crack spread which is calculated assuming that one barrel of Light Louisiana Sweet (“LLS”) crude oil is converted into one-half barrel of Gulf Coast conventional gasoline and one-half barrel of Gulf Coast high sulfur diesel. The Krotz Springs refinery has the capability to process substantial volumes of light sweet, crude oils to produce a high percentage of refined light products.

• The crude oil and product slate flexibility of the El Dorado refinery allows us to take advantage of changes in the crude oil and product markets; therefore, we anticipate that the quantities and varieties of crude oil processed and products manufactured at the El Dorado refinery by processing a variety of feedstocks into a number of refined product types will continue to vary. While there is variability in the crude slate and the product output at the El Dorado refinery, we compare our per barrel refined product margin to the Gulf Coast 5-3-2 crack spread because we believe it to be the most closely aligned benchmark.

A widening of the WTI Cushing less WTI Midland spread will favorably influence the operating margin for our refineries. Alternatively, a narrowing of this differential will have an adverse effect on our operating margins. Global product prices are influenced by the price of Brent crude which is a global benchmark crude. Global product prices influence product prices in the U.S. As a result, our refineries are influenced by the spread between Brent crude and WTI Midland. The Brent less WTI Midland spread represents the differential between the average per barrel price of Brent crude oil and the average per barrel price of WTI Midland crude oil. A widening of the spread between Brent and WTI Midland will favorably influence our refineries' operating margins. Also, the Krotz Springs refinery is influenced by the spread between Brent crude and LLS. The Brent less LLS spread represents the differential between the average per barrel price of Brent crude oil and the average per barrel price of LLS crude oil. A discount in LLS relative to Brent will favorably influence the Krotz Springs refinery operating margin.

Our logistics segment gathers, transports and stores crude oil and markets, distributes, transports and stores refined products in select regions of the southeastern United States and west Texas for our refining segment and third parties. It is comprised of the consolidated balance sheet and results of operations of Delek Logistics Partners, LP ("Delek Logistics", NYSE:DKL), where we owned a 61.4% limited partner interest (at June 30, 2019) in Delek Logistics and a 94.6% interest in the entity that owns the entire 2.0% general partner interest in Delek Logistics and all of the incentive distribution rights. Delek Logistics 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 currently integral to our refining and marketing operations. The logistics segment's pipelines and transportation business owns or leases capacity on approximately 400 miles of crude oil transportation pipelines, approximately 450 miles of refined product pipelines, an approximately 600-mile crude oil gathering system and associated crude oil storage tanks with an aggregate of approximately 9.6 million barrels of active shell capacity. Our logistics segment owns and operates nine light product terminals and markets light products using third-party terminals.

Our retail segment at June 30, 2019 includes the operations of 263 owned and leased convenience store sites located primarily in central and west Texas and New Mexico which were acquired in connection with the Delek/Alon Merger. Our convenience stores typically offer various grades of gasoline and diesel under the Delek or Alon 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 Delek or Alon brand names pursuant to a license agreement with 7-Eleven, Inc. which gives us a perpetual license to use the 7-Eleven trademark, service name and trade name in west Texas and a majority of the counties in New Mexico in connection with our retail store operations. In November 2018, we terminated the license agreement with 7-Eleven, Inc. and the terms of such termination require the removal of all 7-Eleven branding on a store-by-store basis by the earlier of December 31, 2021 or the date upon which our last 7-Eleven store is de-identified or closed. Merchandise sales at our convenience store sites will continue to be sold under the 7-Eleven brand name until 7-Eleven branding is removed pursuant to the termination. 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. In connection with our retail strategic initiatives, we closed or sold 20 under-performing or non-strategic store locations during the six months ended June 30, 2019 and have plans to close 10 additional stores during the remainder of 2019.

Management's Discussion and Analysis

The cost to acquire the refined fuel products we sell to our wholesale customers in our logistics segment and at our convenience stores in our retail segment depends on numerous factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined petroleum products which, in turn, depend on, among other factors, changes in domestic and foreign economies, weather conditions, domestic and foreign political affairs, production levels, the availability of imports, the marketing of competitive fuels and government regulation. Our retail merchandise sales are driven by convenience, customer service, competitive pricing and branding. Motor fuel margin is sales less the delivered cost of fuel and motor fuel taxes, measured on a cents per gallon basis. Our motor fuel margins are impacted by local supply, demand, weather, competitor pricing and product brand.

Our corporate activities, results of certain immaterial operating segments (including Alon's asphalt terminal operations effective with the Delek/Alon Merger), results and assets of discontinued operations and intercompany eliminations are reported in corporate, other and eliminations in our segment disclosure.

As part of our overall business strategy, we regularly evaluate opportunities to expand our portfolio of businesses and may at any time be discussing or negotiating a transaction that, if consummated, could have a material effect on our business, financial condition, liquidity or results of operations.

2019 Developments

Transactions designed to maximize shareholder return

Dividend Declaration

On July 29, 2019, Delek's Board of Directors voted to declare a quarterly cash dividend of $0.29 per share, payable on September 3, 2019, to stockholders of record on August 19, 2019. Our previous quarterly cash dividend amounts ranged between $0.20 to $0.26 per share throughout 2018, was $0.27 for the first quarter 2019 and was $0.28 for the second quarter of 2019.

Share Repurchases

During the three and six months ended June 30, 2019, Delek repurchased 1,647,078 and 2,938,722 shares for an aggregate purchase price of $58.6 million and $104.8 million, respectively, under the most recent share repurchase plan which provided for repurchases up to $500.0 million and was approved by the board on November 6, 2018. As of June 30, 2019, there remained $304.9 million available for repurchases under the most recent repurchase plan.

Transactions designed to maximize return on assets

Alkylation Project Completed

The alkylation unit at the Krotz Springs refinery was completed in early April providing additional flexibility to the refinery. The total cost was approximately $138.0 million. This unit should improve the ability to convert low value products into gasoline, enable the refinery to produce multiple summer gasoline grades and increase octane, allowing the refinery to produce premium gasoline. Because of the conversion improvement at the refinery from this project, its returns are expected to be less dependent on the crack spread environment over time.

Investment in Pipeline Joint Venture

In September 2018, Delek announced plans for a joint venture with Energy Transfer, Magellan, and MPLX to construct a 600-mile common carrier pipeline to transport crude oil from the Permian Basin to the Texas Gulf Coast region (the "Proposed PGC Partnership"). During the first quarter 2019, we elected not to move forward with the Proposed PGC Partnership which allowed us to explore other options to participate in a long-haul crude oil pipeline.

On July 30, 2019, we, through our wholly-owned direct subsidiary Delek US Energy, Inc. (“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 will have a 15% ownership interest in WWP. 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) and it is anticipated that Delek Energy’s capital contributions will total approximately $340 million to $380 million over the course of construction (expected to be two to three years), with an initial capital contribution of $40.0 million due within 30 days of the execution of the LLCA.This investment was made to advance our long-term strategic objectives to expand our midstream investments and network/pipeline access.

Red River Joint Venture

In May 2019, Delek Logistics, through its wholly owned indirect subsidiary Delek Logistics Pipeline, LLC (“Delek Logistics 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, Delek Logistics Pipeline contributed approximately $124.7

Management's Discussion and Analysis

million, substantially all of which was financed under the Delek Logistics Credit Facility, to Red River in exchange for a 33% membership interest in Red River and Delek Logistics Pipeline’s admission as a member of Red River ("Red River Pipeline Joint Venture"). Red River intends to proceed with an expansion project to increase the capacity of the pipeline from 150,000 barrels per day to 235,000 barrels per day and, pursuant to the Contribution Agreement, in May 2019 we contributed an additional $3.5 million for such expansion project. This investment was also made to advance our long-term strategic objectives to expand our midstream investments and network/pipeline access.

Transactions designed to minimize the cost of capital/manage financial risk exposures

2019 Amendments to Supply and Offtake Agreements

During January 2019, we amended the El Dorado refinery and the Krotz Springs refinery Supply and Offtake Agreements with J. Aron & Company ("J. Aron") so that the repurchase of baseline volumes at the end of the applicable Supply and Offtake Agreement term (representing the "Baseline Step-Out Liabilities") will be based upon a fixed price instead of a market-indexed price and therefore subject to changes in fair value that reflect changes in interest rate risk rather than commodity price risk. The modified arrangement results in a Baseline Step-Out Liability that is no longer subject to commodity volatility, but for which its fair value is subject to interest rate risk. As a result, we recorded a gain on the change in fair value resulting from the modification of the instruments from commodities-based risk to interest rate risk in cost of materials and other in the first quarter of 2019. Such Baseline Step-Out Liabilities will continue to be recorded at fair value, where the fair value will reflect changes in interest rate risk rather than commodity price risk. See further discussion in Note 9 of our condensed consolidated financial statements included in Item 1, Financial Statements, of this Quarterly Report on Form 10-Q.

2019 Amendment to the Term Loan Credit Facility Agreement

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%, increasing the aggregate principal amount of loans outstanding under the Term Loan Credit Facility on the First Incremental Effective Date to $943.0 million. Per the Incremental Amendment, the required scheduled quarterly principal payments under the Term Loan Credit Facility increased from $1.750 million to $2.375 million commencing with the quarterly principal payment due on June 28, 2019. The terms of the Incremental Term 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 the proceeds may be used to (i) to reduce utilizations under the Revolving Credit Facility, (ii) for general corporate purposes and (iii) to pay transaction fees and expenses associated with the Incremental Amendment.

Market Trends

Our results of operations are significantly affected by fluctuations in the prices of certain commodities, including, but not limited to, crude oil, gasoline, distillate fuel, biofuels, natural gas and electricity. Historically, our profitability has been affected by commodity price volatility, specifically as it relates to the price of crude oil and refined products.

Management's Discussion and Analysis

As U.S. crude oil production has increased, we have seen the discount for WTI Cushing compared to Brent widen. This generally leads to higher margins in our refineries, as refined product prices are influenced by Brent crude prices and the majority of our crude supply is WTI-linked. The average discount for WTI Cushing compared to Brent increased to $8.78 during the first six months of 2019 from $5.66 during the first six months of 2018. We note similar historical trends when reviewing the discount for WTI Cushing compared to LLS, where the average discount increased to $7.37 during the first six months of 2019 from $3.99 during the first six months of 2018. Additionally, our refineries continue to have relatively greater access to WTI Midland and WTI Midland-linked crude feedstocks compared to certain of our competitors. The average discount for WTI Midland compared to WTI Cushing decreased to $1.71 during the first six months of 2019 from a discount of $4.33 during the first six months of 2018. As these price discounts increase, so does our competitive advantage, created by our access to WTI Midland-linked crude oil pricing. The chart below illustrates the differentials of both Brent crude oil and WTI Midland crude oil as compared to WTI Cushing crude oil for each of the quarterly periods in 2018 and for the two quarterly periods in 2019.

Management's Discussion and Analysis

Environmental regulations continue to affect our margins in the form of volatility in the cost of renewable identification number ("RINs"). On a consolidated basis, we work to balance the cost of our credits for commitments required by the EPA to blend biofuels into fuel products ("RINs Obligation") in order to minimize the effect of RINs on our results. While we generate RINs in both our refining and logistics segments through our ethanol blending and biodiesel production, our refining segment needs to purchase additional RINs to satisfy its obligations. As a result, increases in the price of RINs generally adversely affect our results of operations. It is not possible at this time to predict with certainty what future volumes or costs may be, but given the volatile price of RINs, the cost of purchasing sufficient RINs could have an adverse impact on our results of operations if we are unable to recover those costs in the price of our refined products. The chart below illustrates the volatile nature of the price for RINs for each of the quarterly periods in 2018 and for the two quarterly periods in 2019.

Contractual Obligations

There have been no material changes to our contractual obligations and commercial commitments during the six months ended June 30, 2019, from those disclosed in our Annual Report on Form 10-K.

Critical Accounting Policies

The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. The SEC has defined critical accounting policies as those that are both most important to the portrayal of our financial condition and results of operations, and require our most difficult, subjective or complex judgments or estimates. Based on this definition and as further described in our 2018 Annual Report on Form 10-K, we believe our critical accounting policies include the following: (i) estimating our quarterly inventory adjustments using the last-in, first-out valuation method for the Tyler refinery, (ii) evaluating impairment for property, plant and equipment and definite life intangibles, (iii) evaluating potential impairment of goodwill, (iv) estimating environmental expenditures, and (v) estimating asset retirement obligations. For all financial statement periods presented, there have been no material modifications to the application of these critical accounting policies or estimates since our most recently filed Annual Report on Form 10-K. See Note 1 of the condensed consolidated financial statements in Item 1, Financial Statements for discussion of updates to our accounting policies.

Management's Discussion and Analysis

Non-GAAP Measures

Our management uses certain “non-GAAP” operational measures to evaluate our operating segment performance and non-GAAP financial measures to evaluate past performance and prospects for the future to supplement our GAAP financial information presented in accordance with U.S. GAAP. These financial and operational non-GAAP measures are important factors in assessing our operating results and profitability and include:

• Refining margin - calculated as the difference between net refining revenues and total cost of materials and other;

• Refined product margin - calculated as the difference between net revenues attributable to refined products (produced and purchased) and related cost of materials and other (which is applicable to both the refining segment and the west Texas wholesale marketing activities within our logistics segment); and

• Refining margin per barrels sold - calculated as refining margin divided by our average refining sales in barrels per day (excluding purchased barrels) multiplied by 1,000 and multiplied by the number of days in the period.

We believe these non-GAAP operational and financial measures are useful to investors, lenders, ratings agencies and analysts to assess our ongoing performance because, when reconciled to their most comparable GAAP financial measure, they provide improved comparability between periods through the exclusion of certain items that we believe are not indicative of our core operating performance and they may obscure our underlying results and trends.

Non-GAAP measures have important limitations as analytical tools, because they exclude some, but not all, items that affect net earnings and operating income. These measures should not be considered substitutes for their most directly comparable U.S. GAAP financial measures.

Non-GAAP Reconciliations

The following table provides a reconciliation of refining margin to the most directly comparable U.S.GAAP measure, gross margin:

YTD 2019 vs. YTD 2018

Consolidated net income for the six months ended June 30, 2019 was $238.2 million compared to net income of $61.2 million for the six months ended June 30, 2018. Consolidated net income attributable to Delek for the six months ended June 30, 2019 was $226.6 million, or $2.94 per basic share, compared to net income of $38.7 million, or $0.47 per basic share, for the six months ended June 30, 2018. Explanations for significant drivers impacting net income as compared to the comparable period of the prior year are discussed in the sections below.

Net Revenues

Q2 2019 vs. Q2 2018

In the second quarters of 2019 and 2018, we generated net revenues of $2,480.3 million and $2,636.9 million, respectively, a decrease of $156.6 million, or 5.9%. The decrease in net revenues was primarily driven by the following factors:

• in our refining segment, decreases in the average price of U.S. Gulf Coast gasoline of 8.8%, ULSD of 7.9%, and High-Sulfur diesel ("HSD") of 8.2%;

• in our logistics segment, decreases in the average volume sold and sales prices per gallon of gasoline and diesel sold in our west Texas marketing operations, where the average sales prices per gallon of gasoline and diesel sold decreased $0.26 per gallon and $0.24 per gallon, respectively;

• in our retail segment, decreases in fuel sales volumes and merchandise sales partially attributable to reduction in the average number of stores, and decrease in fuel sales due to a $0.19 decrease in average price charged per gallon; and

• a reduction in revenue from our asphalt business due to the sale of asphalt assets in the second quarter of 2018.

Such decreases were partially offset by:

• increased revenues in our logistics segment associated with our Paline Pipeline as a result of increased rates and a change in the fee structure.

YTD 2019 vs. YTD 2018

For the six months ended June 30, 2019 and 2018, we generated net revenues of $4,680.2 million and $4,990.1 million, respectively, a decrease of $309.9 million, or 6.2%. The decrease in net revenues was primarily driven by the following factors:

• in our refining segment, decreases in the average price of U.S. Gulf Coast gasoline of 11.2%, ULSD of 5.4%, and HSD of 4.8%; and

• in our logistics segment, decreases in the average volume sold and sales prices per gallon of gasoline and diesel sold in our west Texas marketing operations, where the average sales prices per gallon of gasoline and diesel sold decreased $0.21 per gallon and $0.17 per gallon, respectively.

Such decreases were partially offset by:

• increased revenues in our logistics segment associated with our Paline Pipeline as a result of increased rates and a change in the fee structure.

Cost of Materials and Other

Q2 2019 vs. Q2 2018

Cost of materials and other was $2,067.7 million for the second quarter of 2019 compared to $2,250.2 million for the second quarter of 2018, a decrease of $182.5 million, or 8.1%. The net decrease in cost of materials and other was primarily driven by the following:

• decreases in the cost of crude oil feedstocks at the refineries including a decrease in the cost of WTI Cushing crude oil from an average of $68.03 per barrel to an average of $59.80, and a decrease in the cost of WTI Midland crude oil from an average of $59.93 per barrel to an average of $57.56 during the comparable periods;

• a decrease in RIN expense from approximately $35.8 million to income of $1.0 million, where ethanol RIN prices averaged $0.17 per RIN in second quarter 2019 compared to $0.31 per RIN in the prior year period;

• decreases in the cost of refined products in the logistics segment where the average cost per gallon of gasoline and diesel purchased decreased $0.23 per gallon and $0.17 per gallon, respectively;

• a decrease in retail fuel cost of materials and other attributable to a decrease in average cost per gallon of $0.25; and

• an increase in hedging gains to $30.7 million recognized during the second quarter of 2019 from a loss of $13.9 million recognized during the second quarter of 2018.

YTD 2019 vs. YTD 2018

Cost of materials and other was $3,767.1 million for the six months ended June 30, 2019 compared to $4,293.0 million for the six months ended June 30, 2018, a decrease of $525.9 million, or 12.3%. The net decrease in cost of materials and other was primarily driven by the following:

• decreases in the cost of crude oil feedstocks at the refineries including a decrease in the cost of WTI Cushing crude oil from an average of $65.52 per barrel to an average of $57.36, and a decrease in the cost of WTI Midland crude oil from an average of $61.19 per barrel to an average of $55.65 during the comparable periods;

• a decrease in RIN expense where ethanol RIN prices averaged $0.18 per RIN in six months ended June 30, 2019 compared to $0.45 per RIN in the prior year period;

• decreases in the cost of refined products in the logistics segment where the average cost per gallon of gasoline and diesel purchased decreased $0.21 per gallon and $0.13 per gallon, respectively;

• a decrease in retail fuel cost of materials and other attributable to a decrease in average cost per gallon of $0.20; and

• an increase in hedging gains to $50.5 million recognized during the six months ended June 30, 2019 from a loss of $23.2 million recognized during the six months ended June 30, 2018.

Such decreases were partially offset by:

• a prior period benefit of approximately $115.5 million related to a combination of the 2017 RINs waivers and a biodiesel tax credit recognized during the six months ended June 30, 2018 that was not recurring in the six months ended June 30, 2019.

Operating Expenses

Q2 2019 vs. Q2 2018

Operating expenses were $162.3 million for the second quarter of 2019 compared to $157.5 million for the second quarter of 2018, an increase of $4.8 million, or 3.0%. The increase in operating expenses was primarily driven by the following:

• higher employee related costs primarily across our refining and logistics segment; and

• higher outside service costs in our refining segment.

YTD 2019 vs. YTD 2018

Operating expenses were $329.0 million for the six months ended June 30, 2019 compared to $315.6 million for the six months ended June 30, 2018, an increase of $13.4 million, or 4.2%. The increase in operating expenses was primarily driven by the following:

• higher employee related costs primarily in our refining and logistics segments;

• higher contract services in our refining and logistics segments; and

• partially offset by reductions in maintenance expense and chemical expenses in our refining segment.

General and Administrative Expenses

Q2 2019 vs. Q2 2018

General and administrative expenses were $69.5 million for the second quarter of 2019 compared to $52.9 million for the second quarter of 2018, an increase of $16.6 million, or 31.4%. The increase in general and administrative expense was primarily driven by the following:

• an increase in employee costs driven by higher annual incentive plan costs and increased headcount in corporate and other; and

• increases in legal costs associated with various acquisition, investment, litigation and dispute matters; and

• increases for various outside service costs.

YTD 2019 vs. YTD 2018

General and administrative expenses were $131.7 million and $118.1 million for the six months ended June 30, 2019 and 2018, respectively, a increase of $13.6 million, or 11.5%. The increase in general and administrative expense was primarily driven by the following:

• an increase in employee costs driven by higher annual incentive plan costs and increased headcount;

• increases in legal costs associated with various acquisition, investment, litigation and dispute matters;

• increases in supplies expenses for subscriptions and office related costs; and

• increases for various outside service costs.

Depreciation and Amortization

Q2 2019 vs. Q2 2018

Depreciation and amortization (included in both cost of sales and other operating expenses) was $50.1 million for the second quarter of 2019 compared to $49.2 million for the second quarter of 2018, a increase of $0.9 million, or 1.8%.

YTD 2019 vs. YTD 2018

Depreciation and amortization (included in both cost of sales and other operating expenses) was $96.9 million compared to $97.2 million for the six months ended June 30, 2019 and 2018, respectively, a decrease of $0.3 million, or 0.3%.

Other Operating Income, Net

Q2 2019 vs. Q2 2018

Other operating income decreased by $4.4 million in the second quarter of 2019 to $3.6 million compared to expense of $8.0 million in the second quarter of 2018, partially due to higher net gains associated with our Canadian crude trading operations in the second quarter of 2018.

YTD 2019 vs. YTD 2018

Other operating income decreased by $6.5 million during the six months ended June 30, 2019 to $1.2 million compared to income of $7.7 million during the six months ended June 30, 2018, partially due to higher net gains associated with our Canadian crude trading operations in the second quarter of 2018.

Non-operating Expenses, Net

Interest Expense

Q2 2019 vs. Q2 2018

Interest expense increased by $1.3 million, or 4.1%, to $32.8 million in the second quarter of 2019 compared to $31.5 million in the second quarter of 2018, primarily driven by the following:

• an increase in the average effective interest rate of 0.86% in the second quarter of 2019 compared to the second quarter of 2018 (where effective interest rate is calculated as interest expense divided by the net average borrowings/obligations outstanding), partially offset by a decrease in net average borrowings outstanding (including the obligations under the supply and offtake agreements which have an associated interest charge) of approximately $274.6 million in the second quarter of 2019 (calculated as a simple average of beginning borrowings/obligations and ending borrowings/obligations for the period) compared to the second quarter of 2018.

Management's Discussion and Analysis

YTD 2019 vs. YTD 2018

Interest expense decreased by $2.5 million, or 3.9%, to $61.5 million during the six months ended June 30, 2019 compared to $64.0 million during the six months ended June 30, 2018, primarily driven by the following:

• a decrease in the average effective interest rate of 0.26% during the six months ended June 30, 2019 compared to the six months ended June 30, 2018 (where effective interest rate is calculated as interest expense divided by the net average borrowings/obligations outstanding), partially offset by an increase in net average borrowings outstanding (including the obligations under the supply and offtake agreements which have an associated interest charge) of approximately $13.9 million during the six months ended June 30, 2019 (calculated as a simple average of beginning borrowings/obligations and ending borrowings/obligations for the period) compared to the six months ended June 30, 2018.

Results from Equity Method Investments

Q2 2019 vs. Q2 2018

We recognized income of $9.3 million from equity method investments during the second quarter of 2019, compared to $2.9 million for the second quarter of 2018, an increase of $6.4 million. This increase was primarily driven by the following:

• an increase in income from our logistics joint ventures from $1.9 million in the second quarter of 2018 to $4.5 million in the second quarter of 2019, primarily due to the addition of the Red River Joint Venture in May 2019; and

• an increase in income from our asphalt joint venture from $0.9 million in the second quarter of 2018 to $4.7 million in the second quarter of 2019.

YTD 2019 vs. YTD 2018

During the six months ended June 30, 2019, we recognized income of $11.9 million from equity method investments, compared to $2.9 million for the six months ended June 30, 2018, an increase of $9.0 million. This increase was primarily driven by the following:

• an increase in income from our logistics joint ventures from $2.8 million in the first six months of 2018 to $6.5 in the first six months of 2019, primarily due to the addition of the Red River Joint Venture in May 2019; and

• an increase in income from our asphalt joint venture from $0.2 million in the first six months of 2018 to $5.2 million in the first six months of 2019.

Other

Q2 2019 vs. Q2 2018

During the second quarter of 2018, we recognized a gain on the sale of certain asphalt assets totaling $13.2 million which was not present during the three months ended June 30, 2019.

YTD 2019 vs. YTD 2018

During the six months ended June 30, 2018, we incurred certain infrequently occurring expenses/charges that were not incurred during the six months ended June 30, 2019. These included a $9.0 million loss on extinguishment of debt related to the Refinancing and an impairment loss on assets held for sale totaling approximately $27.5 million related to the asphalt assets held for sale. These charges were partially offset by a realized gain on the sale of certain asphalt assets totaling $13.2 million, including a gain on the sale of an asphalt equity method investment. See Notes 7 and 10 of the condensed consolidated financial statements in Item 1, Financial Statements, for additional information.

Income Taxes

Q2 2019 vs. Q2 2018

Income tax expense decreased by $8.2 million in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• pre-tax income of $109.2 million in the second quarter of 2019, as compared to pre-tax income $120.3 million for the second quarter of 2018; and

• a decrease in our effective tax rate which was 22.5% for the second quarter of 2019, compared to 27.3% for the second quarter of 2018 primarily due to the discrete adjustments that were reported in the second quarter of 2018 to properly consider the impact of the Tax Reform Act (which reduced the US federal corporate tax rate from 35% to 21%) on previously recorded deferred taxes.

Management's Discussion and Analysis

YTD 2019 vs. YTD 2018

Income tax expense increased by $49.1 million during the six months ended June 30, 2019 compared to the same period for 2018, primarily driven by the following:

• pre-tax income of $309.4 million for the six months ended June 30, 2019, as compared to pre-tax income of $91.5 million for the six months ended June 30, 2018; and

• a decrease in our effective tax rate which was 22.8% and 23.3% for the six months ended June 30, 2019 and 2018, respectively, primarily due to the discrete adjustments that were reported in the first six months of 2018 for the following:

◦ further adjustments to properly consider the impact of the Tax Reform Act (which reduced the US federal corporate tax rate from 35% to 21%) on previously recorded deferred taxes;

◦ tax benefit for federal tax credits attributable to the Company’s biodiesel blending operations for 2017 that have not been extended by Congress;

◦ tax expense associated with the impairment of assets held for sale; and

◦ changes in valuation allowance attributable to the book-tax basis differences from the Big Spring Logistic Asset Acquisition (See Note 5).

Management's Discussion and Analysis

Operating Segments

We review operating results in the following reportable segments:

• Refining

• Logistics

• Retail

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 its reportable segments based on the segment contribution margin.

Refining Segment

The tables and charts below set forth certain information concerning our refining segment operations ($ in millions, except per barrel amounts):

Refining Segment Margins
	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018 (1)		2019 (1)		2018 (1)
Net revenues	$	2,367.8	$	2,543.2	$	4,459.8	$	4,669.1
Cost of materials and other	2,074.5		2,253.0		3,751.2		4,130.9
Refining margin	293.3		290.2		708.6		538.2

Contribution margin	$	178.3	$	177.0	$	472.6	$	310.3

⁽¹⁾  Refining segment net revenues and cost of materials and other for the three and six months ended June 30, 2018 reflect a correction of an intercompany elimination which resulted in an increase in those accounts of $73.4 million not previously reflected on the unaudited consolidated financial statements in our June 30, 2018 Quarterly Report on Form 10-Q filed on August 9, 2018. Such amounts are not considered material to the financial statements and had no impact to operating income or segment contribution margin for those periods. See Note 23 to our annual audited consolidated financial statements included in Part II, Item 8 of our 2018 Annual Report on Form 10-K, as amended and filed on June 27, 2019, for further discussion.

⁽²⁾  The net revenues, cost of materials and other and refining margin for the six months ended June 30, 2019 excludes Canada trading activity which was previously included and reported in the refining segment for the three months ended March 31, 2018.

Refining Segment Operational Comparison of the Three and Six Months Ended June 30, 2019 versus the Three and Six Months Ended June 30, 2018

Net Revenues

Q2 2019 vs. Q2 2018

Net revenues for the refining segment decreased by $175.4 million, or 6.9%, in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• decreases in the average price of U.S. Gulf Coast gasoline of 8.8%, ULSD of 7.9%, and High-Sulfur diesel ("HSD") of 8.2%; and

• decreases in sales volume of refined product totaling 3.2 million barrels consisting of decreases in sales volumes at our El Dorado refinery primarily resulting from the scheduled turnaround activities and decreases in sales volumes at the other refineries related to unit outages or maintenance stoppages, offset by a 3.2 million barrel increase in purchased product sales across all four refineries primarily to compensate for production shortfalls.

Net revenues included sales to our retail segment of $101.7 million and $118.9 million, sales to our logistics segment of $73.2 million and $99.5 million and sales to our other segment of $40.4 million and $7.7 million for the three months ended June 30, 2019 and June 30, 2018, respectively. We eliminate this intercompany revenue in consolidation.

YTD 2019 vs. YTD 2018

Net revenues for the refining segment decreased by $209.3 million, or 4.5%, in the six months ended June 30, 2019 compared to the six months ended June 30, 2018, primarily driven by the following:

• decreases in the average price of U.S. Gulf Coast gasoline of 11.2%, ULSD of 5.4%, and HSD of 4.8%; and

• decreases in sales volume of refined product totaling 3.7 million barrels consisting of decreases in sales volumes at our El Dorado refinery primarily resulting from the scheduled turnaround activities and decreases in sales volumes at the Tyler and Krotz Springs refineries related to unit outages or maintenance stoppages, offset by a 1.8 million barrel increase in sales volumes of refined product at our Big Spring refinery and a 5.7 million barrel increase in purchased product sales across all four refineries primarily to compensate for production shortfalls.

Net revenues included sales to our retail segment of $191.9 million and $218.4 million, sales to our logistics segment of $152.6 million and $181.8 million and sales to our other segment of $55.4 million and $11.1 million for the six months ended June 30, 2019 and 2018, respectively.

Cost of Materials and Other

Q2 2019 vs. Q2 2018

Cost of materials and other decreased by $178.5 million, or 7.9%, in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• a decrease in the cost of WTI Cushing crude oil, from an average of $68.03 per barrel to an average of $59.80, or 12.1%;

• a decrease in the cost of WTI Midland crude oil, from an average of $59.93 per barrel to an average of $57.56, or 4.0%; and

• a decrease in RIN expense from approximately $32.8 million to income of $1.0 million, where ethanol RIN prices averaged $0.17 per RIN in second quarter 2019 compared to $0.31 per RIN in the prior year period.

YTD 2019 vs. YTD 2018

Cost of materials and other decreased by $379.7 million, or 9.2%, during the six months ended June 30, 2019 compared to the six months ended June 30, 2018, primarily driven by the following:

• a decrease in the cost of WTI Cushing crude oil, from an average of $65.52 per barrel to an average of $57.36, or 12.5%;

• a decrease in the cost of WTI Midland crude oil, from an average of $61.19 per barrel to an average of $55.65, or 9.1%; and

• the net reversal benefit of $51.5 million related to inventory valuation reserves recognized during the six months ended June 30, 2019 compared to the net reversal benefit of $1.9 million recognized during the six months ended June 30, 2018.

These decreases were partially offset by the following:

• a prior period benefit of approximately $115.5 million related to a combination of the 2017 RINs waivers and a biodiesel tax credit recognized during the six months ended June 30, 2018 that was not recurring in the same period of 2019.

Our refining segment purchases finished product from our logistics segment and has multiple service agreements with our logistics segment which, among other things, require the refining segment to pay terminalling and storage fees based on the throughput volume of crude and finished product in the logistics segment pipelines and the volume of crude and finished product stored in the logistics segment storage tanks, subject to minimum volume commitments. These costs and fees were $52.2 million and $43.6 million during the second quarters of 2019 and 2018, respectively, and $104.4 million and $97.9 million during the six months ended June 30, 2019 and 2018, respectively. We eliminate these intercompany fees in consolidation.

Refining Margin

Q2 2019 vs. Q2 2018

Refining margin increased by $3.1 million, or 1.1%, in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• wider discounts between WTI Cushing crude oil compared to Brent which impact refining margin at all four refineries where, during the second quarter of 2019, the average WTI Cushing crude oil differential to Brent crude oil was $8.64 per barrel compared to $6.93 during the second quarter of 2018;

• a 7.9% improvement in the 5-3-2 crack spread (the primary measure for the Tyler refinery and El Dorado refinery);

• a 5.4% improvement in the average Gulf Coast 3-2-1 crack spread (the primary measure for the Big Spring refinery); and

• the benefit attributable to the decrease in RIN prices.

These increases were partially offset by the following:

• a narrowing of the average WTI Cushing crude oil differential to WTS crude oil to $1.87 per barrel during the second quarter of 2019 compared to $8.50 during the second quarter of 2018 and narrowing of the average WTI Midland crude oil differential to WTI Cushing crude oil to $2.24 per barrel during the second quarter of 2019 compared to $8.10 during the second quarter of 2018;

• a narrowing of the discount between WTI Midland crude oil and Brent crude oil where, during the second quarter of 2019, the WTI Midland crude oil differential to Brent crude oil was an average discount of $10.88 per barrel compared to $15.03 per barrel during the second quarter of 2018; and

• a 10.0% decline in the average Gulf Coast 2-1-1 crack spread (the primary measure for the Krotz Springs refinery).

Q2 2019 vs. Q2 2018

Contribution margin decreased by $1.2 million, or 2.6%, in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• lower sales volumes combined with a $1.81 decrease in gross margin per gallon of our gasoline and diesel sold in our west Texas marketing operations; and

• a slight increase in operating expenses.

YTD 2019 vs. YTD 2018

Contribution margin increased by $2.6 million, or 3.2%, in the six months ended June 30, 2019 compared to the six months ended June 30, 2018, primarily driven by the following:

• increases in revenue generated under the agreements executed in connection with the Big Spring Logistic Assets Acquisition.

Such increases were partially offset by the following:

• higher operating expenses; and

• decreases in the volumes of gasoline and diesel sold in our west Texas marketing operations.

Retail Segment Operational Comparison of the Three and Six Months Ended June 30, 2019 versus the Three and Six Months Ended June 30, 2018

Net Revenues

Q2 2019 vs. Q2 2018

Net revenues for the retail segment decreased by $20.3 million, or 8.3%, in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• total fuel sales were $140.8 million in the second quarter of 2019 compared to $152.0 million in the second quarter of 2018, attributable to the following:

◦ a $0.19 decrease in average price charged per gallon; and

◦ a slight decrease in total retail fuel gallons sold for the retail segment to 53,743 thousand gallons in the second quarter of 2019 compared to 54,114 thousand gallons in the second quarter of 2018 associated with the reduction in average number of stores period over period, where there was a same-store sales growth in fuel volumes of 1.7 %;

• merchandise sales were $83.3 million in the second quarter of 2019 compared to $90.2 million in the second quarter of 2018 which was impacted by the reduction in average number of stores period over period and included a same-store sales decrease of 2.5%.

YTD 2019 vs. YTD 2018

Net revenues for the retail segment decreased by $32.7 million, or 7.2%, in the six months ended June 30, 2019 compared to the six months ended June 30, 2018, primarily driven by the following:

• total fuel sales were $262.7 million in the six months of 2019 compared to $280.9 million in the six months of 2018, attributable to the following:

◦ a $0.17 decrease in average price charged per gallon; and

◦ relative consistency in total retail fuel gallons sold of 107,633 thousand gallons in the six months of 2019 compared to 107,813 thousand gallons in the six months of 2018, where the consistent volumes are attributable to a decrease in volumes associated with the reduction in average number of stores period over period offset by same-store sales growth in fuel volumes of 3.1 %.

• merchandise sales were $158.6 million in the six months of 2019 compared to $168.3 million in the six months of 2018 which was impacted by the reduction in average number of stores period over period and included a same-store sales decrease of 0.5%.

Cost of Materials and Other

Q2 2019 vs. Q2 2018

Cost of materials and other for the retail segment decreased by $18.8 million, or 9.4%, in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• a decrease in average cost per gallon of $0.25 or 9.7% applied to fuel sales volumes that decreased slightly period over period.

Our retail segment purchased finished product from our refining segment of $101.7 million and $118.9 million for the three months ended June 30, 2019 and June 30, 2018, respectively, attributable to the reduction in the number of stores. We eliminate this intercompany cost in consolidation.

YTD 2019 vs. YTD 2018

Cost of materials and other for the retail segment decreased by $28.6 million, or 7.6%, in the six months ended June 30, 2019 compared to the six months ended June 30, 2018, primarily driven by the following:

• a decrease in average cost per gallon of $0.20 or 8.2% applied to fuel sales volumes that remained relatively consistent period over period.

Our retail segment purchased finished product from our refining segment of $191.9 million and $218.4 million for the six months ended June 30, 2019 and June 30, 2018, respectively, attributable to the reduction in the number of stores. We eliminate this intercompany cost in consolidation.

Operating Expenses

Q2 2019 vs. Q2 2018

Operating expenses for the retail segment decreased by $0.5 million, or 2.0% in the second quarter of 2019 compared to the second quarter of 2018. This decrease is primarily attributable to a decrease in operating costs associated with the reduction in the number of stores.

YTD 2019 vs. YTD 2018

Operating expenses for the retail segment decreased by $1.4 million, or 2.8% in the six months ended June 30, 2019 compared to the six months ended June 30, 2018. This decrease is primarily attributable to a decrease in operating costs associated with the reduction in the number of stores.

Contribution Margin

Q2 2019 vs. Q2 2018

Contribution margin for the retail segment decreased by $1.0 million, a 5.4% decline in contribution margin percentage, in the second quarter of 2019 compared to the second quarter of 2018, primarily driven by the following:

• a decline in fuel revenues primarily attributable to the $0.19 decline in average price charged per gallon of retail fuel sold;

• a decline in merchandise revenues largely attributable to the reduction in the number of average stores; and

• partially offset by $0.057 per gallon improvement in the retail fuel margin.

YTD 2019 vs. YTD 2018

Contribution margin for the retail segment decreased by $2.7 million, a 8.9% decline in contribution margin percentage, in the six months ended June 30, 2019 compared to the six months ended June 30, 2018, primarily driven by the following:

• a decline in fuel revenues primarily attributable to the $0.17 decline in average price charged per gallon of retail fuel sold;

• a decline in merchandise revenues largely attributable to the reduction in the number of average stores;

• a decline in same-store contribution margin of 13.2%; and

• partially offset by $0.034 per gallon improvement in the retail fuel margin.

Management's Discussion and Analysis

Liquidity and Capital Resources

Our primary sources of liquidity are

• cash generated from our operating activities;

• borrowings under our debt facilities; and

• potential issuances of additional equity and debt securities.

We believe that cash generated from these sources will be sufficient to satisfy the anticipated cash requirements associated with our existing operations and capital expenditures for at least the next 12 months.

Cash Flows

The following table sets forth a summary of our consolidated cash flows (in millions):

Consolidated
	Six Months Ended June 30,
	2019			2018
Cash Flow Data:
Operating activities	$	235.4		$	(136.4	)
Investing activities	(329.4		)	13.8
Financing activities	(33.9		)	313.5
Net (decrease) increase	$	(127.9	)	$	190.9

Cash Flows from Operating Activities

Net cash provided by operating activities was $235.4 million for the six months ended June 30, 2019, compared to net cash used of $136.4 million for the comparable period of 2018. The increase in cash flows from operations was partially due to an increase in net income, which for the six months ended June 30, 2019 was $238.2 million, compared to $61.2 million in the same period of 2018. Additionally, net income for the six months ended June 30, 2019 included a non-cash expense for deferred income taxes of $16.0 million compared to a benefit of $65.3 million in the prior year. Also, contributing $134.9 million to the increase was the change in fair value of derivatives.

Cash Flows from Investing Activities

Net cash used in investing activities was $329.4 million for the first six months of 2019, compared to net cash received of $13.8 million in the comparable period of 2018. The increase in cash flows used in investing activities was primarily due to an increase in cash purchases of property, plant and equipment and capital expenditures related to turnaround activities, which increased from $142.5 million in 2018, to $199.9 million in 2019, and a $136.2 million increase in equity method investment contributions in the current year, $124.7 million of which related to our obtaining a 33% membership interest in Red River Red River Pipeline Joint Venture in May 2019. Also contributing to this increase was the sale of asphalt assets and discontinued operations in 2018, for which we received proceeds of $110.8 million and $39.7 million, respectively.

Cash Flows from Financing Activities

Net cash used in financing activities was $33.9 million for the six months ended June 30, 2019, compared to net cash provided of $313.5 million in the comparable 2018 period. The decrease in net cash provided by financing activities was partially due to the decrease in net proceeds received from long-term revolvers due to completion of the Refinancing transaction as well as the additional borrowings used to fund the Big Spring Logistic Assets Acquisition during the six months ended June 30, 2018. We made net payments on long-term revolvers of $85 million during the six months ended June 30, 2019 compared to net proceeds received of $552 million in the comparable 2018 period. Partially offsetting this decrease was a decrease in repurchase of common stock to $104.8 million for the six months ended June 30, 2019 compared to $115.3 million in the comparable 2018 period, as well as a decrease in repayments of product financing arrangements to $15.6 million for the six months ended June 30, 2019 compared to $72.4 million in the comparable 2018 period.

Cash Position and Indebtedness

As of June 30, 2019, our total cash and cash equivalents were $951.4 million and we had total indebtedness of approximately $1,916.7 million. Total unused credit commitments or borrowing base availability, as applicable, under our revolving credit facilities was approximately $911.1 million and we had letters of credit issued of approximately $267.2 million. We believe we were in compliance with our covenants in

78 |

all debt facilities as of June 30, 2019. See Note 10 of the condensed consolidated financial statements in Item 1, Financial Statements, for additional information about our separate credit facilities.

Capital Spending

A key component of our long-term strategy is our capital expenditure program. Our capital expenditures for the six months ended June 30, 2019 were $214.3 million, of which approximately $130.5 million was spent in our refining segment, $2.2 million in our logistics segment, $10.5 million in our retail segment and $71.1 million at the holding company level. The following table summarizes our actual capital expenditures for the six months ended June 30, 2019 and planned capital expenditures for the full year 2019 by operating segment and major category (in millions):

	Full Year 2019 Forecast		Six Months Ended June 30, 2019
Refining
Sustaining maintenance, including turnaround activities	$	138.4	$	74.5
Regulatory	63.1		22.7
Discretionary projects	37.3		33.3
Refining segment total	238.8		130.5
Logistics
Regulatory	3.4		0.7
Sustaining maintenance	4.6		0.9
Discretionary projects	0.8		0.6
Logistics segment total	8.8		2.2
Retail
Regulatory	—		—
Sustaining maintenance	3.5		2.3
Discretionary projects	17.4		8.2
Retail segment total	20.9		10.5
Other
Regulatory	1.5		0.4
Sustaining maintenance	1.6		0.5
Discretionary projects	124.6		70.2
Other total	127.7		71.1
Total capital spending	$	396.2	$	214.3

The amount of our capital expenditure budget is subject to change due to unanticipated increases in the cost, scope and completion time for our capital projects. For example, we may experience increases in the cost of and/or timing to obtain necessary equipment required for our continued compliance with government regulations or to complete improvement projects or scheduled maintenance activities. Additionally, the scope and cost of employee or contractor labor expense related to installation of that equipment could exceed our projections. Our capital expenditure budget may also be revised as management continues to evaluate projects for reliability or profitability.

We have no off-balance sheet arrangements through the date of the filing of this Quarterly Report on Form 10-Q.

Management's Discussion and Analysis

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

These disclosures should be read in conjunction with the condensed consolidated financial statements, "Management's Discussion and Analysis of Financial Condition and Results of Operations," and other information presented herein, as well as in the "Quantitative and Qualitative Disclosures About Market Risk" section contained in our Annual Report on Form 10-K, as amended and filed on June 27, 2019.

Price Risk Management Activities

At times, we enter into the following instruments/transactions in order to manage our market-indexed pricing risk: commodity derivative contracts which we use to manage our price exposure to our inventory positions, future purchases of crude oil and ethanol, future sales of refined products or to fix margins on future production; and future commitments to purchase or sell RINs at fixed prices and quantities, which are used to manage the costs associated with our RINs obligations and meet the definition of derivative instruments under ASC 815, Derivatives and Hedging ("ASC 815"). In accordance with ASC 815, all of these commodity contracts and future purchase commitments are recorded at fair value, and any change in fair value between periods has historically been recorded in the profit and loss section of our condensed consolidated financial statements. Occasionally, at inception, the Company will elect to designate the commodity derivative contracts as cash flow hedges under ASC 815. Gains or losses on commodity derivative contracts accounted for as cash flow hedges are recognized in other comprehensive income on the condensed consolidated balance sheets and, ultimately, when the forecasted transactions are completed, in net revenues or cost of materials and other in the condensed consolidated statements of income.

The following table sets forth information relating to our open commodity derivative contracts as of June 30, 2019 ($ in millions):

	Total Outstanding			Notional Contract Volume by Year of Maturity

Management's Discussion and Analysis

Interest Risk Management Activities

We have market exposure to changes in interest rates relating to our outstanding floating rate borrowings, which totaled approximately $1,612.3 million as of June 30, 2019. The annualized impact of a hypothetical one percent change in interest rates on our floating rate debt as of June 30, 2019 would be to change interest expense by approximately $16.1 million.

Commodity Derivatives Trading Activities

In the first half of 2018, we began entering into active trading positions in a variety of commodity derivatives, which include forward physical contracts, swap contracts, and futures contracts. These contracts are classified as held for trading and are recognized at fair value with changes in fair value recognized in the income statement. Trading activities are undertaken by using a range of contract types in combination to create incremental gains by capitalizing on crude oil supply and pricing seasonality. These contracts had remaining durations of less than one year as of June 30, 2019.

The following table sets forth information relating to commodity derivative contracts held for trading purposes as of June 30, 2019:

Contract Description	Less than 1 year
Over the counter forward sales contracts
Notional contract volume (1)	1,042,953
Weighted-average market price (per barrel)	$	44.43
Contractual volume at fair value (in millions)	$	46.3
Over the counter forward purchase contracts

ITEM 4. CONTROLS AND PROCEDURES

Our disclosure controls and procedures are designed to provide reasonable assurance that the information that we are required to disclose in reports we file under the Securities Exchange Act of 1934, as amended ("the Exchange Act"), is accumulated and appropriately communicated to management. We carried out an evaluation required by Rule 13a-15(b) of the Exchange Act, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures at the end of the reporting period. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the reporting period.

There have been no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the second quarter of 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

Organization and Basis of Presentation

Delek US Holdings, Inc. operates through its consolidated subsidiaries, which include Delek US Energy, Inc. (and its subsidiaries) and Alon USA Energy, Inc. ("Alon") (and its subsidiaries).

Effective July 1, 2017 (the "Effective Time"), we acquired the outstanding common stock of Alon (previously listed under NYSE: ALJ) (the "Delek/Alon Merger", as further discussed in Note 2), resulting in a new post-combination consolidated registrant renamed as Delek US Holdings, Inc. (“New Delek”), with Alon and the previous Delek US Holdings, Inc. (“Old Delek”) surviving as wholly-owned subsidiaries. New Delek is the successor issuer to Old Delek and Alon pursuant to Rule 12g-3(c) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). In addition, as a result of the Delek/Alon Merger, the shares of common stock of Old Delek and Alon were delisted from the New York Stock Exchange ("NYSE") in July 2017, and their respective reporting obligations under the Exchange Act were terminated.

Unless otherwise indicated or the context requires otherwise, the disclosures and financial information included in this report for the periods prior to July 1, 2017 reflect that of Old Delek, and the disclosures and financial information included in this report for the periods beginning July 1, 2017 reflect that of New Delek. The terms "we," "our," "us," "Delek" and the "Company" are used in this report to refer to Old Delek and its consolidated subsidiaries for the periods prior to July 1, 2017, and New Delek and its consolidated subsidiaries for the periods on or after July 1, 2017, unless otherwise noted. New Delek's Common Stock is listed on the NYSE under the symbol "DK."

Our condensed consolidated financial statements include the accounts of Delek and its subsidiaries. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited consolidated financial statements included in our Annual Report on Form 10-K as amended and filed with the Securities and Exchange Commission ("SEC") on June 27, 2019 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2018 included in our Annual Report on Form 10-K.

Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics"), which is a variable interest entity. 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.

In the opinion of management, all adjustments necessary for a fair presentation of the financial condition and the results of operations for the interim periods have been included. All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year.

Reclassifications

Certain prior period amounts have been reclassified in order to conform to the current period presentation. Additionally, certain changes to presentation of the prior period statements of income have been made in order to conform to the current period presentation, primarily relating to the addition of a subtotal entitled 'cost of sales' which includes all costs directly attributable to the generation of the related revenue, as defined by GAAP, and the retitling of what was previously referred to as 'cost of goods sold' to 'cost of materials and other'. In connection with this change in presentation, we revised our related accounting policy, as presented in our 2018 Annual Report on Form 10-K.

New Accounting Pronouncements Adopted During 2019

Accounting Standards Update ("ASU") 2016-02, Leases

In February 2016, the Financial Accounting Standards Board (the "FASB") issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial condition for all leases with terms longer than one year. The guidance was subsequently amended to consider the impact of practical expedients and provide additional clarifications. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We adopted the new lease standard on January 1, 2019. We elected the package of practical expedients which, among other things, allows us to carry forward the historical lease classification. For certain lease classes, we have elected the practical expedient not to separate lease and non-lease components, which allows us to combine the components if certain criteria are met. Further, we elected the optional transition method, which allows us to recognize a cumulative-effect adjustment to the opening balance sheet of retained earnings at the date of adoption and to not recast our comparative periods. We have not elected the hindsight practical expedient, which would have allowed us to use hindsight in determining the reasonably certain lease term. The adoption of the lease accounting guidance had no impact on January 1, 2019 retained earnings and resulted in the recognition of a $211.0 million lease liability and a corresponding right-of-use asset on our consolidated balance sheet. The adoption did not have a material impact on our consolidated income statement. See Note 20 for further information.

ASU 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities

In August 2017, the FASB issued guidance to better align financial reporting for hedging activities with the economic objectives of those activities for both financial (e.g., interest rate) and commodity risks. The guidance was intended to create more transparency in the presentation of financial results, both on the face of the financial statements and in the footnotes, and simplify the application of hedge accounting guidance. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Companies are required to apply the guidance on a modified retrospective transition method in which the cumulative effect of the change is recognized within equity in the consolidated balance sheet as of the date of adoption. We adopted this guidance on January 1, 2019 and the adoption did not have a material impact on our business, financial condition or results of operations. See Note 11 for further information.

Accounting Pronouncements Not Yet Adopted

ASU 2018-15, Intangible - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

In August 2018, the FASB issued guidance related to customers’ accounting for implementation costs incurred in a cloud computing arrangement that is considered a service contract. This pronouncement aligns the requirements for capitalizing implementation costs in such arrangements with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued. Entities can choose to adopt the new guidance prospectively or retrospectively. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition and results of operations.

ASU 2018-14, Compensation - Changes to the Disclosure Requirements for Defined Benefit Plans

In August 2018, the FASB issued guidance related to disclosure requirements for defined benefit plans. The pronouncement eliminates, modifies and adds disclosure requirements for defined benefit plans. The pronouncement is effective for fiscal years ending after December 15, 2020, and early adoption is permitted. We expect to adopt this guidance on or before the effective date and do not expect adopting this new guidance will have a material impact on our business, financial condition or results of operations.

ASU 2018-13, Fair Value Measurement - Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued guidance related to disclosure requirements for fair value measurements. The pronouncement eliminates, modifies and adds disclosure requirements for fair value measurements. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. We expect to adopt this guidance on or before the effective date and do not expect adopting this new guidance will have a material impact on our business, financial condition or results of operations.

ASU 2016-13, Financial Instruments - Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued guidance requiring the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Organizations will now use forward-looking information to better inform their credit loss estimates. This guidance is effective for interim and annual periods beginning after December 15, 2019. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition and results of operations.

Business Combinations [Abstract]

Acquisitions

Acquisitions

In January 2017, we announced that Old Delek (and various related entities) entered into a merger agreement with Alon, as amended (the "Merger Agreement"). The related Merger (as previously defined, the "Delek/Alon Merger") was effective July 1, 2017 (as previously defined, the “Effective Time”), resulting in a new post-combination consolidated registrant renamed as Delek US Holdings, Inc. (as previously defined, “New Delek”), with Alon and Old Delek surviving as wholly-owned subsidiaries of New Delek. New Delek is the successor issuer to Old Delek and Alon pursuant to Rule 12g-3(c) under the Exchange Act, as amended. In addition, as a result of the Delek/Alon Merger, the shares of common stock of Old Delek and Alon were delisted from the NYSE in July 2017, and their respective reporting obligations under the Exchange Act were terminated.

In connection with the Delek/Alon Merger, Alon, New Delek and U.S. Bank National Association, as trustee (the “Trustee”) entered into a First Supplemental Indenture (the “Supplemental Indenture”), effective as of July 1, 2017, which provided for Alon's 3.00% Convertible Senior Notes due 2018, which were previously convertible into Alon Common Stock, to thereafter be convertible into New Delek Common Stock based on the exchange rate applied in the Delek/Alon Merger (the “Convertible Notes”). Additionally, in connection with the Convertible Notes, Alon also entered into equity instruments, including call options (the "Call Options") and warrants (the "Warrants"), designed, in combination, to hedge a portion of the risk associated with the potential exercise of the conversion feature of the Convertible Notes and to mitigate the dilutive effect of such potential conversion. These instruments were also exchanged in connection with the Delek/Alon Merger into instruments that were indexed to New Delek Common Stock. See Note 10 for further discussion of these instruments and subsequent activity.

The Delek/Alon Merger was accounted for using the acquisition method of accounting, which requires, among other things, that assets acquired and liabilities assumed be recognized on the balance sheet at their fair values as of the acquisition date. Transaction costs incurred by the Company in connection with the Delek/Alon Merger totaled $1.8 million and $6.6 million for the three and six months ended June 30, 2018, respectively. Such costs were included in general and administrative expenses in the accompanying condensed consolidated statements of income.

The final allocation of the aggregate purchase price (which was finalized as of June 30, 2018) is summarized as follows (in millions), and is inclusive of our discontinued Paramount and Long Beach, California refinery and California renewable fuels facility operations (collectively, the "California Discontinued Entities," discussed in Note 7):

Delek common stock issued	19,250,795
Ending price per share of Delek Common Stock immediately before the Effective Time	$	26.44
Total value of common stock consideration			$	509.0
Additional consideration (1)			21.7
Fair value of Delek's pre-existing equity method investment in Alon (2)			449.0
			979.7
Less: Fair value of net assets acquired			109.0
Goodwill (excess of purchase price over fair value of net assets acquired)			$	870.7

⁽¹⁾   Additional consideration includes the fair value of certain equity instruments originally indexed to Alon stock that were exchanged for instruments indexed to New Delek's stock, as well as the fair value of certain share-based payments that were required to be exchanged for awards indexed to New Delek's stock in connection with the Delek/Alon Merger.

⁽²⁾ The fair value of Delek's pre-existing equity method investment in Alon was based on the quoted market price of shares of Alon.

During the three and six months ended June 30, 2018, certain immaterial catch-up adjustments were recorded related to accretion of environmental liabilities and amortization of leasehold intangibles identified and valued during the final months of the measurement period.

Segment Reporting [Abstract]

Segment Data

Segment Data

We aggregate our operating units 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 consist of the following: our corporate activities; results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 11); Alon's asphalt terminal operations acquired as part of the Delek/Alon Merger and subsequently substantially disposed in the second quarter of 2018 (see Note 7 for further discussion); the California Discontinued Entities which were acquired as part of the Delek/Alon Merger and subsequently disposed over the first seven months of 2018 (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. Segment contribution margin is defined as net revenues less cost of materials and other and operating expenses, excluding depreciation and amortization.

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 June 30, 2019, including the 75,000 bpd Tyler, Texas refinery (the "Tyler refinery"), the 80,000 bpd El Dorado, Arkansas refinery (the "El Dorado refinery"), the 73,000 bpd Big Spring, Texas refinery (the "Big Spring refinery"), and the 74,000 bpd Krotz Springs, Louisiana refinery (the "Krotz Springs refinery"), as well as a non-operating refinery located in Bakersfield, California. The refining segment also owns and operates two biodiesel facilities involved in the production of biodiesel fuels and related activities, located in Crossett, Arkansas and Cleburn, Texas. The refining segment's petroleum-based products are marketed primarily in the south central, southwestern and western regions of the United States, and the refining 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, we sell motor fuels through our wholesale distribution network on an unbranded basis.

Our refining segment has service agreements with our logistics segment, which, among other things, requires the refining segment to pay service fees based on the number of gallons sold and to share a portion of the margin achieved in return for providing marketing, sales and customer services at the Tyler refinery, and effective March 1, 2018, at the Big Spring refinery (see Note 5 for further discussion regarding the Big Spring marketing agreement). These intercompany transaction fees in regards to the Tyler refinery were $5.1 million and $9.9 million during the three and six months ended June 30, 2019, respectively, and $5.5 million and $10.5 million during the three and six months ended June 30, 2018, respectively. The intercompany transaction fees in regards to the Big Spring refinery were $3.4 million and $7.0 million for the three and six months ended June 30, 2019, respectively, and $3.2 million and $4.3 million for the three and six months ended June 30, 2018, respectively. Additionally, the refining segment purchases finished product and pays crude transportation, terminalling and storage fees to the logistics segment for the utilization of pipeline, terminal and storage assets, including, effective March 1, 2018, those related to the Big Spring Logistic Assets Acquisition discussed further in Note 5. These costs and fees were $52.2 million and $104.4 million during the three and six months ended June 30, 2019, respectively, and $43.6 million and $97.9 million during the three and six months ended June 30, 2018, respectively. The logistics segment also sold $0.4 million and $0.8 million of renewable identification numbers ("RINs") to the refining segment during the three and six months ended June 30, 2019, respectively, and $0.7 million and $2.0 million during the three and six months ended June 30, 2018, respectively. The refining segment recorded refined product sales revenues from the retail segment of $101.7 million and $191.9 million during the three and six months ended June 30, 2019, respectively, and $118.9 million and $218.4 million during the three and six months ended June 30, 2018, respectively. The refining segment includes refined product sales revenues from our logistics segment of $73.2 million and $152.6 million during the three and six months ended June 30, 2019, respectively, and $99.5 million and $181.8 million during the three and six months ended June 30, 2018, respectively. The refining segment also includes sales revenues of $40.4 million and $55.4 million from sales of asphalt and refined product to entities included in corporate, other and eliminations during the three and six months ended June 30, 2019, respectively, and $7.7 million and $11.1 million during the three and six months ended June 30, 2018.

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. The logistics segment is currently managing a long-term capital project on our behalf for the construction of a gathering system in the Permian Basin. Pursuant to the agreement(s) governing these services, the logistics segment received management fees of $1.1 million and $2.8 million during the three and six months ended June 30, 2019, respectively, from corporate for the management of this project. The logistics segment incurs some of the costs in connection with the construction of the assets and is subsequently reimbursed by corporate.

Our retail segment consists of approximately 263 owned and leased convenience store sites as of June 30, 2019, located primarily in central and west Texas and New Mexico. These convenience stores typically offer various grades of gasoline and diesel primarily 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 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. In November 2018, we terminated the license agreement with 7-Eleven, Inc. and the terms of such termination require the removal of all 7-Eleven branding on a store-by-store basis by the earlier of December 31, 2021 or the date upon which our last 7-Eleven store is de-identified or closed. 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 pursuant to the termination. In connection with certain strategic initiatives, we closed or sold 20 under-performing or non-strategic store locations during the six months ended June 30, 2019. As a result of these transactions, we expect to receive total proceeds of $9.9 million, of which $5.8 million was received in the six months ended June 30, 2019, and recognized gains of a nominal amount and $2.1 million during the three and six months ended June 30, 2019,

respectively, which are included in other operating income, net in the accompanying condensed consolidated statements of income. We wrote-off goodwill associated with these retail stores of $1.2 million in the three and six months ended June 30, 2019.

All inter-segment transactions have been eliminated in consolidation.

Earnings (Loss) Per Share

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Earnings (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 periods presented, we have outstanding various equity-based compensation awards that are considered in our diluted EPS calculation (when to do so would be dilutive), and is inclusive of awards disclosed in Note 17 to these condensed 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. Additionally, in connection with the Delek/Alon Merger, we assumed certain equity instruments, including conversion options (associated with the Convertible Notes) and Warrants, that may be dilutive (see discussion of these instruments in Note 10). The Convertible Notes conversion options were dilutive during the period they were outstanding when the incremental EPS calculated by dividing the increase in income associated with the elimination of interest expense on the convertible debt, net of tax, by the number of shares that would be issued upon conversion using the treasury stock method (which is applicable because of the cash settlement feature associated with the underlying principal) is dilutive to the overall diluted EPS calculation. The Warrants are generally dilutive during the period they are outstanding when the market price of the underlying indexed share of common stock is in excess of the exercise price. All such instruments that may otherwise be dilutive may not be dilutive when there is a net loss for the period. On September 17, 2018, Delek settled the Convertible Notes for a combination of cash and shares of New Delek Common Stock (See Note 10) and in November 2018, Delek entered into Warrant Unwind Agreements (the "Unwind Agreements" - See Note 10) with the holders of our outstanding common stock warrants; therefore, these instruments were only potentially dilutive for EPS for the three and six months ended June 30, 2018.

The following table sets forth the computation of basic and diluted earnings per share.

Variable Interest Entity [Abstract]

Delek Logistics and the Alon Partnership

Delek Logistics and the Alon Partnership

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 June 30, 2019, we owned a 61.4% limited partner interest in Delek Logistics, consisting of 15,294,046 common

units, and a 94.6% interest in Delek Logistics GP, LLC, which owns the entire 2.0% general partner interest, consisting of 498,312 general partner units, in Delek Logistics and all of the incentive distribution rights.

The limited partner interests in Delek Logistics not owned by us are reflected in net income attributable to non-controlling interest in the accompanying condensed consolidated statements of income and in non-controlling interest in subsidiaries in the accompanying condensed consolidated balance sheets.

In March 2018, a subsidiary of Delek Logistics completed the acquisition from a subsidiary of Delek (the "Alon Partnership") of storage tanks and terminals that support the Big Spring refinery (the "Big Spring Logistic Assets Acquisition"), which included the execution of related commercial agreements. In addition, a new marketing agreement was entered into between the subsidiary of Delek Logistics and the Alon Partnership pursuant to which the subsidiary of Delek Logistics provides marketing services for product sales from the Big Spring refinery. The cash paid for the transferred assets was $170.8 million, subject to certain post-closing adjustments, and the cash paid for the marketing agreement was $144.2 million. The transactions were financed with borrowings under the 2014 Facility revolving credit agreement (as defined in Note 10). Additionally, the transaction resulted in the creation of a deferred tax asset related to the tax-book basis difference in the sold assets totaling $98.8 million, against which we have recorded a valuation allowance totaling $5.5 million for the portion of the deferred tax asset that relates to basis difference attributable to the non-controlling interest and therefore may not be realizable. Prior periods have not been recast in our Segment Data Note 3, as these assets did not constitute a business in accordance with ASU 2017-01, Clarifying the Definition of a Business, and were accounted for as acquisitions of assets between entities under common control.

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, including new agreements related to the Big Spring Logistic Assets Acquisition. The revenues and expenses associated with these agreements are eliminated in consolidation.

Delek Logistics is a variable interest entity, as defined under GAAP, and is consolidated into our condensed consolidated financial statements, representing our logistics segment. Exclusive of intercompany balances and the marketing agreement intangible asset between Delek Logistics and Delek which are eliminated in consolidation, the Delek Logistics condensed consolidated balance sheets as presented below are included in the condensed consolidated balance sheets of Delek (unaudited, in millions).

Alon Partnership

As part of the Delek/Alon Merger, we acquired a majority interest in the Alon Partnership, which owns the assets and conducts the operations of the Big Spring refinery and the associated integrated wholesale marketing operations. On February 7, 2018 (the "Merger Date"), Delek acquired from the Alon Partnership all of the outstanding limited partner units that Delek did not already own in an all-equity transaction (the "Alon Partnership Merger"). Delek owned approximately 51.0 million limited partner units of the Alon Partnership, or approximately 81.6% of the outstanding units, immediately prior to the Merger Date. Under terms of the merger agreement, the owners of the remaining outstanding units in the Alon Partnership that Delek did not own immediately prior to the Merger Date received a fixed exchange ratio of 0.49 shares of New Delek common stock for each limited partner unit of the Alon Partnership, resulting in the issuance of approximately 5.6 million shares of New Delek common stock to the public unitholders of the Alon Partnership. Because the transaction represented a combination of ownership interests under common control, the transfer of equity from non-controlling interest to owned interest (additional paid-in capital) was recorded at carrying value and no gain or loss was recognized in connection with the transaction. Additionally, book-tax basis difference was created as a result of the transaction that resulted in a deferred tax asset of approximately $13.5 million, net of a valuation allowance on certain state income tax components, that also increased additional paid-in capital. Transaction costs incurred by the Company in connection with the Alon Partnership Merger totaled approximately $3.0 million for the six months ended June 30, 2018, none of which were recorded in the second quarter of 2018. Such costs were included in general and administrative expenses in the accompanying condensed consolidated statements of income.

Prior to the Merger Date, the Alon Partnership was a variable interest entity for which Delek was the primary beneficiary. As of June 30, 2019 and December 31, 2018, the Alon Partnership is included in Delek's condensed consolidated balance sheet as a wholly-owned subsidiary.

Equity Method Investments and Joint Ventures [Abstract]

Equity Method Investments

Equity Method Investments

In May 2019, Delek Logistics, through its wholly owned indirect subsidiary Delek Logistics Pipeline, LLC (“Delek Logistics 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, Delek Logistics 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 Delek Logistics 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, with an expansion project planned to increase the pipeline capacity, which is expected to be completed during the first half of 2020. Delek Logistics contributed an additional $3.5 million related to such expansion project in May 2019.

Delek Logistics also has two joint ventures that own and operate logistics assets, and which serve third parties and subsidiaries of Delek. As of June 30, 2019 and December 31, 2018, Delek Logistics' investment balances in these joint ventures totaled $241.6 million and $104.8 million, respectively, and were accounted for using the equity method.

Delek Renewables, LLC, a wholly-owned subsidiary of Delek, has 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 June 30, 2019 and December 31, 2018, Delek Renewables, LLC's investment balance in this joint venture was $4.0 million and $2.4 million, respectively, and was accounted for using the equity method. The investment in this joint venture is reflected in the refining segment.

Effective with the Delek/Alon Merger, we acquired a 50% interest in two joint ventures that own asphalt terminals located in Fernley, Nevada, and Brownwood, Texas. On May 21, 2018, Delek sold its 50% interest in the asphalt terminal located in Fernley, Nevada. See Note 7 for further discussion. As of June 30, 2019 and December 31, 2018, Delek's investment balance in the Brownwood, Texas joint venture was $28.0 million and $23.1 million, respectively. This investment is accounted for using the equity method and is included as part of total assets in corporate, other and eliminations in our segment disclosure.

Discontinued Operations and Assets Held for Sale

Discontinued Operations and Assets Held for Sale

Asphalt Terminals Held for Sale

On February 12, 2018, Delek announced it had reached a definitive agreement to sell certain assets and operations of four asphalt terminals (included in corporate, other and eliminations in our segment disclosure), as well as an equity method investment in an additional asphalt terminal located in Femley, Nevada, to an affiliate of Andeavor. On May 21, 2018, Delek completed the transaction and received net proceeds of approximately $110.8 million, inclusive of the $75.0 million base proceeds as well as certain working capital adjustments. The assets associated with the owned terminals met the definition of held for sale pursuant to ASC 360 as of February 1, 2018, but did not meet the definition of discontinued operations pursuant to ASC 205-20, Presentation of Financial Statements - Discontinued Operations ("ASC 205-20"), as the sale of these asphalt assets did not represent a strategic shift that would have a major effect on the entity's operations and

financial results. Accordingly, depreciation ceased as of February 1, 2018, and the assets to be sold were reclassified to assets held for sale as of that date and were written down to the estimated fair value less costs to sell, resulting in an impairment loss on assets held for sale of $27.5 million for the six months ended June 30, 2018 (none for the three months ended June 30, 2018). All goodwill associated with the asphalt operations sold was written off in connection with the impairment charge discussed above. In connection with the completion of the sale transaction in the second quarter of 2018, we recognized a gain of approximately $13.2 million, resulting primarily from the recognition of certain additional proceeds at closing associated with the asphalt terminals which were not previously determinable/probable and the recognition of the gain on the sale of the joint venture which was not previously recognized as held for sale (as it did not meet the criteria).

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 and our California renewable fuels facility (as previously defined, the "California Discontinued Entities"). Such operations were designated and reported as discontinued operations. On March 16, 2018, Delek sold to World Energy, LLC (i) all of Delek’s membership interests in the California renewable fuels facility ("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. Upon final settlement (excluding contingent components), Delek expects to receive net cash proceeds of approximately $85.2 million, which includes a post-closing working capital settlement, Delek’s portion of the biodiesel tax credit for 2017 and certain customary adjustments. The sale resulted in a loss on sale of discontinued operations totaling approximately $41.4 million of which $41.2 million was recorded during the six months ended June 30, 2018 (none for the three months ended June 30, 2018). Of the total expected proceeds, $54.6 million was received in March 2018 ($14.9 million of which were included in net cash flows from investing activities in discontinued operations). As of June 30, 2019, we have received a total of $70.4 million of the total expected proceeds, and have a remaining receivable from the buyer totaling approximately $14.8 primarily related to the working capital settlement. Additionally, Delek will be entitled to its pro rata portion of any tax credits relating to AltAir activities in 2018 earned through the sale date if the 2018 biodiesel tax credit is re-enacted. A receivable for such additional contingent proceeds will be recorded when the criteria for recognition are met, which is predicated upon reenactment of the tax credit and determination of the amounts earned by AltAir.

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 resulting in initial cash proceeds of approximately $14.5 million, net of expenses, and resulting in a gain on sale of discontinued operations of approximately $1.4 million during the third quarter of 2018.

The operating results, net of tax, from discontinued operations associated with the California Discontinued Entities are presented separately in Delek’s condensed consolidated statements of income and the notes to the condensed consolidated financial statements have been adjusted to exclude the discontinued operations. Components of amounts reflected in income (loss) from discontinued operations prior to their disposal are as follows (in millions):

	Three Months Ended			Six Months Ended

⁽¹⁾   Included in loss from discontinued operations is net income attributable to non-controlling interest totaling $8.1 million related to AltAir for the six months ended June 30, 2018 (none for the three months ended June 30, 2018).

Related to the California Discontinued Entities, all of which were disposed of by December 31, 2018, we retained certain obligations associated with various matters, including (but not necessarily limited to) California emissions credits requirements that were attributable to operations of the California Discontinued Entities for periods prior to disposition, litigations, claims or assessments related to matters/events that occurred prior to disposition, or indemnification of certain liabilities that related to the California Discontinued Entities and arose prior to

disposition. Of these matters, we recorded related liabilities of $6.0 million and $5.0 million as of June 30, 2019 and December 31, 2018, respectively based on amounts that were deemed probable and could be reasonably estimated as of those dates. During the three and six months ended June 30, 2019, we recorded an additional accrual for California emission credit obligation based upon our revised estimates totaling $3.4 million. Additionally, in July 2019, we resolved a pending litigation matter (the Ten-Tex Litigation -- see Note 13) that resulted in a decrease in our accrual totaling $2.4 million during the three and six months ended June 30, 2019 (inclusive of the impact of our estimate of the liability for plaintiff legal fees). Such adjustments are included in loss from discontinued operations on the accompanying condensed consolidated statements of income for those periods.

Inventory Disclosure [Abstract]

Inventory

Inventory

Crude oil, work in process, refined products, blendstocks and asphalt inventory for all of our operations, excluding the Tyler refinery and fuel inventory in our retail segment, are stated at the lower of cost determined using the first-in, first-out (“FIFO”) basis or net realizable value. Cost of all inventory at the Tyler refinery is determined using the last-in, first-out ("LIFO") inventory valuation method and inventory is stated at the lower of 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.

Carrying value of inventories consisted of the following (in millions):

	June 30, 2019		December 31, 2018
Refinery raw materials and supplies	$	413.7	$	289.0
Refinery work in process	85.0		58.9
Refinery finished goods	356.9		304.1
Retail fuel	7.1		8.0
Retail merchandise	24.2		25.4
Logistics refined products	4.7		5.5
Total inventories	$	891.6	$	690.9

At June 30, 2019, we recorded a pre-tax inventory valuation reserve of $2.5 million, $1.1 million of which related to LIFO inventory due to a market price decline below our cost of certain inventory products. At December 31, 2018, we recorded a pre-tax inventory valuation reserve of $54.0 million, $39.4 million of which related to LIFO inventory, which reversed in the first quarter of 2019 due to the sale of inventory quantities that gave rise to the December 31, 2018 reserve. We recognized a net (increase) reduction in cost of materials and other in the accompanying condensed consolidated statements of income related to the change in pre-tax inventory valuation of $(0.6) million and $51.5 million for the three and six months ended June 30, 2019, respectively, and $1.0 million and $1.9 million for the three and six months ended June 30, 2018, respectively.

Crude Oil Supply and Inventory Purchase Agreement

6 Months Ended

Other Liabilities Disclosure [Abstract]

Crude Oil Supply and Inventory Purchase Agreement

Crude Oil Supply and Inventory Purchase Agreements

Delek has various Supply and Offtake Agreements (the "Supply and Offtake Agreements") with J. Aron & Company ("J. Aron").

El Dorado Supply and Offtake Agreement

The El Dorado refinery's Supply and Offtake Agreement as amended and restated on February 27, 2017 and in effect through December 2018 (the "El Dorado Supply and Offtake Agreement") provided for Lion Oil Company ("Lion Oil") (as the primary legal entity associated with the El Dorado refinery for purposes of this Agreement) and J. Aron to identify mutually acceptable contracts for the purchase of crude oil from third parties and J. Aron to supply up to 100,000 bpd of crude oil to the El Dorado refinery. Crude oil supplied to the El Dorado refinery by J. Aron is purchased daily at an estimated average monthly market price by Lion Oil. J. Aron will also purchase all refined products from the El Dorado refinery at an estimated daily market price, as they are produced. These daily purchases and sales are trued-up on a monthly basis in order to reflect actual average monthly prices. We have recorded a receivable related to this monthly settlement of $9.0 million and $7.8 million as of June 30, 2019 and December 31, 2018, respectively. Also pursuant to the El Dorado Supply and Offtake Agreement and other related agreements, Lion Oil arranges potential sales by either Lion Oil or J. Aron to third parties of the products produced at the El Dorado refinery or purchased from third parties. In instances where Lion Oil is the seller to such third parties, J. Aron will first transfer title of the applicable products to Lion Oil. The El Dorado Supply and Offtake Agreement has a maturity date of April 30, 2020. Based upon terms in effect as of December 31, 2018, upon the expiration or upon any earlier termination, Delek would be required to repurchase the consigned crude oil and refined products from J. Aron at then prevailing market prices.

Effective January 3, 2019, we amended the El Dorado Supply and Offtake Agreement with J. Aron that supports the operations of our El Dorado refinery so that the repurchase of baseline volumes at the end of the El Dorado Supply and Offtake Agreement term (representing the El Dorado "Baseline Step-Out Liability") will be based upon a fixed price instead of a market-indexed price. The modified arrangement results in a Baseline Step-Out Liability that is no longer subject to commodity volatility, but for which its fair value is now subject to interest rate risk. As a result, we recorded a gain on the change in fair value resulting from the modification of the instruments from commodities-based risk to interest rate risk in cost of materials and other totaling approximately $4.1 million in the first quarter of 2019, and we incurred $3.2 million in fees paid to J. Aron which were charged to interest expense. Such Baseline Step-Out Liability will continue to be recorded at fair value, where the fair value will reflect changes in interest rate risk rather than commodity price risk under the fair value election provided by ASC 815 Derivatives and Hedging ("ASC 815") and ASC 825, Financial Instruments ("ASC 825"). The change in fair value recorded during the three and six months ended June 30, 2019 related to the new instrument totaled $0.9 million and $(1.6) million, respectively, and is reflected as a increase (reduction) in interest expense.

At June 30, 2019 and December 31, 2018, Delek had 3.3 million barrels and 2.8 million barrels, respectively, of inventory consigned from J. Aron under the El Dorado Supply and Offtake Agreement, and we have recorded total liabilities associated with this consigned inventory of $178.8 million and $152.6 million, respectively, on the condensed consolidated balance sheets. As a result of the amendment to the El Dorado Supply and Offtake Agreement, as of June 30, 2019, the fair value of the Baseline Step-Out Liability totaling $104.5 million is reflected as a current obligation on our condensed consolidated balance sheet, and represents 2.0 million barrels of baseline consigned inventory. We maintained letters of credit with respect to the El Dorado Supply and Offtake Agreement totaling $150.0 million and $120.0 million at June 30, 2019 and December 31, 2018, respectively.

This arrangement is accounted for as a product financing. Delek incurred recurring fees payable to J. Aron under the El Dorado Supply and Offtake Agreement of $3.2 million and $5.7 million during the three and six months ended June 30, 2019, respectively, and $2.9 million and $5.6 million during the three and six months ended June 30, 2018, respectively. These amounts are included as a component of interest expense in the condensed consolidated statements of income. Upon any termination of the El Dorado Supply and Offtake Agreement, including in connection with a force majeure event, the parties are required 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.

Alon Supply and Offtake Agreements

Effective with the Delek/Alon Merger, we assumed Alon's existing Supply and Offtake Agreements and other associated agreements with J. Aron to support the operations of our Big Spring and Krotz Springs refineries and certain of our asphalt terminals (together, the “Alon Supply and Offtake Agreements”). Pursuant to the Alon Supply and Offtake Agreements, (i) J. Aron agreed to sell to us, and we agreed to buy from J. Aron, at market prices, crude oil for processing at these refineries and (ii) we agreed to sell, and J. Aron agreed to buy, at market prices, certain refined products produced at these refineries. The Alon Supply and Offtake Agreements also provide for the sale, at market prices, of our crude oil and certain refined product inventories to J. Aron, 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. The Alon Supply and Offtake Agreements have initial terms that expire in May 2021. J. Aron or Delek may elect to terminate the agreements at the Big Spring and Krotz Springs refineries in May 2020 on six months prior notice. The daily purchases and sales are trued-up on a monthly basis in order to reflect actual average monthly prices. We have recorded a net receivable (payable) related to this monthly settlement of $(10.6) million and $(1.0) million as of June 30, 2019 and December 31, 2018, respectively. Based upon terms in effect prior to the December 2018 and January 2019 amendments discussed below, upon the expiration or upon any earlier termination, Delek would be required to repurchase the consigned crude oil and refined products from J. Aron at then prevailing market prices.

Effective December 21, 2018, we amended our Supply and Offtake Agreement related to the Big Spring refinery (the "Big Spring Supply and Offtake Agreement") so that the repurchase of baseline volumes at the end of the Supply and Offtake Agreement term (representing the Big Spring "Baseline Step-Out Liability") will be based upon a fixed price instead of a market-indexed price. The modified arrangement results in a Baseline Step-Out Liability that is no longer subject to commodity volatility, but for which its fair value is now subject to interest rate risk. As a result for the Big Spring Supply and Offtake Agreement, we recorded a gain on the change in fair value resulting from the modification of the instruments from commodities-based risk to interest rate risk in cost of materials and other in the fourth quarter of 2018. Such Baseline Step-Out Liability will continue to be recorded at fair value, where the fair value will reflect changes in interest rate risk rather than commodity price risk under the fair value election provided by ASC 815 and ASC 825. Fees paid to J Aron as a result of this transaction were recorded as interest expense. As of June 30, 2019 and December 31, 2018 , the fair value of the Baseline Step-Out Liability for the Big Spring refinery was $48.3 million and $49.6 million, respectively, each based on 0.8 million barrels of baseline consigned inventory. As a result of the amendment, as of both June 30, 2019 and December 31, 2018, this baseline consigned inventory for the Big Spring refinery is reflected as a non-current obligation on our condensed consolidated balance sheet. The change in fair value recorded during the three and six months ended June 30, 2019 related to the new instrument totaled $0.2 million and $(1.3) million, respectively, and is reflected as a increase (reduction) in interest expense. There were no changes in our credit spread during the period that would require recognition in accumulated other comprehensive income pursuant to ASC 825.

At June 30, 2019 and December 31, 2018, Delek had 1.4 million barrels and 1.7 million barrels, respectively, of inventory consigned from J. Aron under the Big Spring Supply and Offtake Agreement, and we have recorded total liabilities associated with this consigned inventory of $77.4 million and $96.5 million, respectively, on the condensed consolidated balance sheets.

Effective January 2, 2019, we amended our Supply and Offtake Agreement related to the Krotz Springs refinery (the "Krotz Springs Supply and Offtake Agreement") so that the repurchase of baseline volumes at the end of the Supply and Offtake Agreement term (representing the Krotz Springs "Baseline Step-Out Liability") will also be based upon a fixed price instead of a market-indexed price. Like the Big Spring amendment, this modified arrangement results in a Baseline Step-Out Liability that is no longer subject to commodity volatility, but for which its fair value is now subject to interest rate risk. As a result for the Krotz Springs Supply and Offtake Agreement, we recorded a gain on the change in fair value resulting from the modification of the instruments from commodities-based risk to interest rate risk in cost of materials and other of $3.5 million in the first quarter of 2019, and we incurred $1.8 million in fees paid to J Aron which were charged to interest expense. Such Baseline Step-Out Liability will continue to be recorded at fair value, where the fair value will reflect changes in interest rate risk rather than commodity price risk under the fair value election provided by ASC 815 and ASC 825.

At June 30, 2019, Delek had 1.9 million barrels of inventory consigned from J. Aron under the Krotz Springs Supply and Offtake Agreement, inclusive of both the baseline volumes and over, short and excess target quantities, and we have total recorded liabilities associated with this consigned inventory of $124.3 million in the condensed consolidated balance sheets. As a result of the amendment, as of June 30, 2019, the fair value of the Baseline Step-Out Liability totaling $74.5 million for the Krotz Springs refinery is reflected as a non-current obligation on our condensed consolidated balance sheet, and represents 1.3 million barrels of baseline consigned inventory. The change in fair value recorded during the three and six months ended June 30, 2019 related to the new instrument totaled $0.3 million and $(0.8) million, respectively, and is reflected as a increase (reduction) in interest expense. There were no changes in our credit spread during the period that would require recognition in accumulated other comprehensive income pursuant to ASC 825.

Based upon terms in effect as of December 31, 2018 for the Krotz Springs Supply and Offtake Agreement, as of December 31, 2018, we had 1.8 million barrels of inventory consigned from J. Aron under the Krotz Springs Supply and Offtake Agreement, inclusive of both the baseline volumes and over, short and excess target quantities, and recorded a current liability associated with this consigned inventory of $113.1 million in the consolidated balance sheets, measured using the fair value election pursuant to ASC 825 (based on prevailing market-indexed pricing).

Both the Big Spring Supply and Offtake Agreement and the Krotz Springs Supply and Offtake Agreement are accounted for as product financing arrangements. Delek incurred recurring fees payable to J. Aron of $4.1 million and $7.9 million during the three and six months ended June 30, 2019, respectively, and $3.6 million and $6.9 million for the three and six months ended June 30, 2018, respectively. These amounts are included as a component of interest expense in the condensed consolidated statements of income. Upon any termination of the Alon Supply and Offtake Agreements, including in connection with a force majeure event, the parties are required 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.

We maintain letters of credit totaling $44.0 million and $24.0 million, as of June 30, 2019 and December 31, 2018, respectively with respect to the Alon Supply and Offtake Agreements. In connection with the Krotz Springs Supply and Offtake Agreement, we have granted a security interest to J. Aron in certain assets (including all of its accounts receivable and inventory) to secure our obligations to J. Aron.

Outstanding Obligations/Facilities as of the Balance Sheet Dates

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 $300.0 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.

In connection with the Refinancing, we recorded a loss on extinguishment of debt totaling approximately $9.0 million all of which was recorded in the first quarter of 2018.

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%, increasing the aggregate principal amount of loans outstanding under the Term Loan Credit Facility on the First Incremental Effective Date to $943.0 million. The terms of the Incremental Term 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 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 Amendment.

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 London Interbank Offered Rate ("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")). The initial applicable margin for all Term Loan Credit Facility borrowings was 1.50% per annum with respect to base rate borrowings and 2.50% per annum with respect to LIBOR borrowings.

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 borrowings under (i) Base Rate Loans from 1.50% to 1.25% and (ii) LIBOR Rate Loans from 2.50% to 2.25%, as such terms are defined in the Term Loan Credit Facility. 

The initial applicable margin for Revolving Credit Facility borrowings was 0.25% per annum with respect to base rate borrowings and 1.25% per annum with respect to LIBOR and CDOR borrowings, and the applicable margin for such borrowings after September 30, 2018 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, where the fee is at a rate of 0.25% or 0.375% per annum, depending on average commitment usage for such quarter. As of June 30, 2019, the unused line fee was 0.375% per annum.

Maturity and Repayments

The Revolving Credit Facility will mature and the commitments thereunder will terminate on March 30, 2023. Pursuant to Incremental Amendment, the Term Loan Credit Facility requires scheduled quarterly principal payments which increased from $1.750 million to $2.375 million commencing with the quarterly principal payment due on June 28, 2019, with the balance of the principal due on March 30, 2025.

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 prepayments with a variable percentage of Delek’s excess cash flow, ranging from 50.0% to 0% depending on Delek’s consolidated secured net leverage ratio from time to time. Delek may also make voluntarily prepayments under the Term Loan Credit Facility at any time, subject to a prepayment premium of 1.0% in connection with certain customary repricing events that may occur within six months after the First Incremental Effective Date, with no premium applied after six months.

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 Partners, LP, 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, renewable identification numbers, 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 June 30, 2019, the weighted average borrowing rate under the Revolving Credit Facility was 5.75% and was comprised entirely of a base rate borrowing, and the principal amount outstanding thereunder was $75.0 million. Additionally, there were letters of credit issued of approximately $267.2 million as of June 30, 2019 under the Revolving Credit Facility. Unused credit commitments under the Revolving Credit Facility, as of June 30, 2019, were approximately $657.8 million.

At June 30, 2019, the weighted average borrowing rate under the Term Loan Credit Facility was approximately 4.58% comprised entirely of a LIBOR borrowing, and the principal amount outstanding thereunder was $940.6 million. As of June 30, 2019, the effective interest rate related to the Term Loan Credit Facility was 4.90%.

Delek Logistics Credit Facility

Prior to its amendment and restatement on September 28, 2018, Delek Logistics had a $700.0 million senior secured revolving credit agreement with Fifth Third Bank ("Fifth Third"), as administrative agent, and a syndicate of lenders (the "2014 Facility") with a $100.0 million accordion feature, bearing 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. 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 as administrative agent and a syndicate of lenders (hereafter, the "Delek Logistics Credit Facility"). Under the terms of the Delek Logistics Credit Facility, among other things, the lender commitments were increased from $700.0 million to $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. Additionally, a subsidiary of Delek continues to provide a limited guaranty of Delek Logistics' obligations under the Delek Logistics Credit Facility. The guaranty is (i) limited to an amount equal to the principal amount, plus unpaid and accrued interest, of a promissory note made by Delek in favor of the subsidiary guarantor (the "Holdings Note") and (ii) secured by the subsidiary guarantor's pledge of the Holdings Note to the Delek Logistics Credit Facility lenders. As of both June 30, 2019 and December 31, 2018, the principal amount of the Holdings Note was $102.0 million.

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 June 30, 2019, the weighted average borrowing rate was approximately 4.9%. 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 June 30, 2019, this fee was 0.40% per year.

As of June 30, 2019, Delek Logistics had $596.7 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 June 30, 2019, were $253.3 million.

Delek Logistics Notes

On May 23, 2017, Delek Logistics and Delek Logistics Finance Corp. (collectively, the “Issuers”) issued $250.0 million in aggregate principal amount of 6.75% senior notes due 2025 (the “Delek Logistics Notes”) at a discount. The Delek Logistics Notes are general unsecured senior obligations of the Issuers. The Delek Logistics Notes are unconditionally guaranteed jointly and severally on a senior unsecured basis by Delek Logistics' existing subsidiaries (other than Delek Logistics Finance Corp., the "Guarantors") and will be unconditionally guaranteed on the same basis by certain of Delek Logistics' future subsidiaries. The Delek Logistics Notes rank equal in right of payment with all existing and future senior indebtedness of the Issuers, and senior in right of payment to any future subordinated indebtedness of the Issuers. Interest on the Delek Logistics Notes is payable semi-annually in arrears on each May 15 and November 15, commencing November 15, 2017.

At any time prior to May 15, 2020, the Issuers may redeem up to 35% of the aggregate principal amount of the Delek Logistics Notes with the net cash proceeds of one or more equity offerings by Delek Logistics at a redemption price of 106.750% of the redeemed principal amount, plus accrued and unpaid interest, if any, subject to certain conditions and limitations. Prior to May 15, 2020, the Issuers may redeem all or part of the Delek Logistics Notes at a redemption price of the principal amount plus accrued and unpaid interest, if any, plus a "make whole" premium, subject to certain conditions and limitations. In addition, beginning on May 15, 2020, the Issuers may, subject to certain conditions and limitations, redeem all or part of the Delek Logistics Notes, at a redemption price of 105.063% of the redeemed principal for the twelve-month period beginning on May 15, 2020, 103.375% for the twelve-month period beginning on May 15, 2021, 101.688% for the twelve-month period beginning on May 15, 2022 and 100.00% beginning on May 15, 2023 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 Issuers will be obligated to make an offer for the purchase of the Delek Logistics Notes from holders at a price equal to 101.00% of the principal amount thereof, plus accrued and unpaid interest.

In May 2018, the Delek Logistics Notes were exchanged for new notes with terms substantially identical in all material respects with the 2025 Notes except the new notes do not contain terms with respect to transfer restrictions.

As of June 30, 2019, we had $250.0 million in outstanding principal amount under the Delek Logistics Notes. As of June 30, 2019, the effective interest rate related to the Delek Logistics Notes was 7.24%.

Reliant Bank Revolver

Delek has an unsecured revolving credit agreement with Reliant Bank (the "Reliant Bank Revolver") that provides for unsecured loans of up to $30.0 million. The Reliant Bank Revolver matures June 28, 2020, bears interest at fixed rate of 4.75% per annum and requires us to pay a quarterly fee of 0.50% per year on the average unused revolving commitment. As of June 30, 2019, we had $30.0 million outstanding and had no unused credit commitments under the Reliant Bank Revolver

Promissory Notes

On May 14, 2015, in connection with the Company’s closing of the acquisition of an equity method investment in Alon (the "Alon Acquisition"), the Company issued a promissory note (the "Alon Israel Note") in the amount of $145.0 million, which was payable to Alon Israel Oil Company, Ltd. ("Alon Israel"). The Alon Israel Note bears interest at a fixed rate of 5.50% per annum and requires five annual principal amortization payments of $25.0 million beginning in January 2016 followed by a final principal amortization payment of $20.0 million at maturity on January 4, 2021. In October 2015, we prepaid the first annual principal amortization payment in the amount of $25.0 million, along with all interest due on the prepaid amount. On December 22, 2015, Alon Israel assigned the remaining $120.0 million of principal and all accrued interest due under the Alon Israel Note to assignees under four new notes in substantially the same form and on the same terms as the Alon Israel Note (collectively, the "Alon Successor Notes"). The $120.0 million total principal of the four Alon Successor Notes collectively require the same principal amortization payments and schedule as under the Alon Israel Note, with payments due under each Alon Successor Note commensurate to such note's pro rata share of the $120.0 million in assigned principal. As of June 30, 2019, a total principal amount of $45.0 million was outstanding under the Alon Successor Notes.

Restrictive Covenants

Under the terms of our Revolving Credit Facility, Term Loan Credit Facility, Delek Logistics Credit Facility, Delek Logistics Notes and Reliant Bank Revolver, 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 June 30, 2019.

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. Specifically, these covenants may limit the payment, in the form of cash or other assets, of dividends or other distributions, or the repurchase of shares with respect to the equity of the Company or certain of our subsidiaries. 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.

Instruments Outstanding as of June 30, 2018

Alon Convertible Senior Notes

In connection with the Delek/Alon Merger, Alon, New Delek and U.S. Bank National Association, as trustee (the “Trustee”) entered into a First Supplemental Indenture (the “Supplemental Indenture”), effective as of July 1, 2017, which provided that Alon's 3.00% Convertible Senior Notes due September 2018, which were previously convertible into Alon Common Stock, to thereafter be convertible into New Delek Common Stock based on the exchange rate applied in the Delek/Alon Merger (as previously defined, the “Convertible Notes”). Additionally, In connection with the Convertible Notes, Alon also entered into equity instruments, including call options (as previously defined, the "Call Options") and warrants (as previously defined, the "Warrants"), designed, in combination, to hedge a portion of the economic risk associated with the potential exercise of the conversion feature of the Convertible Notes and to mitigate the dilutive effect of such potential conversion. The aggregate principal amount of the Convertible Notes was $150.0 million, and the effective interest rate as of June 30, 2018 was 5.92%, resulting in recognition of total interest expense during the three and six months then ended of approximately $2.2 million and $4.4 million, respectively.

The Convertible Notes could be converted into shares of Delek Common Stock, into cash, or into a combination of cash and shares of New Delek Common Stock, at our election. In May 2018, we made the election and notified holders of our intention to satisfy the principal amount outstanding with cash and the incremental value of the conversion options with shares at maturity. The conversion rate of the Convertible Notes was subject to adjustment upon the occurrence of certain events, including cash dividend adjustments. On September 17, 2018, Delek settled the Convertible Notes for a combination of cash and shares of New Delek Common Stock. The maturity settlement in respect of the Convertible Notes consisted of (i) cash payments totaling approximately $152.5 million which included a cash payment for outstanding principal of $150.0 million, a cash payment for accrued interest of approximately $2.2 million, a cash payment for dividends of approximately $0.3 million and a nominal cash payment in lieu of fractional shares, and (ii) the issuance of approximately 2.7 million shares of New Delek Common Stock to holders of the Convertible Notes (the “Conversion Shares”). The issuance of the Conversion Shares was made in exchange for the

Convertible Notes pursuant to an exemption from the registration requirements provided by Section 3(a)(9) of the Securities Act of 1933, as amended.

Prior to the conversion, the conversion feature met the definition for recognition as a bifurcated equity instrument. At June 30, 2018, the conversion feature equity instrument totaled $26.6 million and was included in additional paid-in capital on the accompanying condensed consolidated balance sheets.

Convertible Note Hedge Transactions

In connection with the Convertible Notes offering, Alon entered into convertible note hedge transactions with respect to Alon Common Stock (as previously defined, the “Call Options”) with the initial purchasers of the Convertible Notes (the “Hedge Counterparties”). In connection with the Delek/Alon Merger, Alon, Delek and the Hedge Counterparties entered into amended and restated Call Options permitting us to purchase up to approximately 5.7 million shares of New Delek Common Stock, subject to customary anti-dilution adjustments, that underlie the Convertible Notes sold in the offering.

On September 17, 2018, we exercised the Call Options in connection with the settlement of the Convertible Notes and received approximately 2.7 million shares of our common stock from the Call Option counterparties, a cash payment for dividends of approximately $0.3 million and a nominal cash payment in lieu of fractional shares. On a net basis, the settlement of the Convertible Notes and the exercise of the Call Options resulted in no net dilution to our common stock. Prior to their exercise, the Call Options totaling $23.3 million were included as a reduction of additional paid-in capital on the condensed consolidated balance sheets.

Warrant Transactions

In connection with the Convertible Notes offering, Alon also entered into warrant transactions (as previously defined, the “Warrants”) whereby warrants to acquire Alon common stock were sold to the Hedge Counterparties. In connection with the Delek/Alon Merger, Alon, Delek and the Hedge Counterparties entered into amended and restated Warrants which allow the Hedge Counterparties to purchase up to approximately 5.7 million shares of New Delek Common Stock, subject to customary anti-dilution adjustments. In November 2018, Delek entered into Warrant Unwind Agreements (as previously defined, the "Unwind Agreements") with the holders of our outstanding common stock Warrants. Pursuant to the terms of the Unwind Agreements, we settled for cash all outstanding Warrants with the holders at various prices per Warrant as provided in the Unwind Agreements. The settlement amount was based on the volume-weighted average market price of our common stock taking into account an adjustment for the exercise price of the Warrants over a period of sixteen trading days beginning November 9, 2018 (the “Unwind Period”). Following the Unwind Period and upon the satisfaction of the payment obligation, the Warrants were canceled and the associated rights and obligations terminated. Based on the provisions of the Unwind Agreements, the amount paid to warrant holders in satisfaction of the payment obligation totaled approximately $36.0 million.

Obligations Extinguished in Connection with the March 2018 Refinancing

Prior to the Refinancing, Delek had outstanding various credit facilities/debt instruments as follows:

Wells ABL

Our subsidiary, Delek Refining, Ltd., had an asset-based loan credit facility with Wells Fargo Bank, National Association, as administrative agent, and a syndicate of lenders, which was previously amended and restated on September 29, 2016 and on May 17, 2017 (the "Wells ABL"). This facility was amended and restated on March 30, 2018 in connection with the Refinancing. The Wells ABL consisted of (i) a $450.0 million revolving loan (the "Wells Revolving Loan") and (ii) a $70 million term loan ("Wells Term Loan"). Borrowings under the Wells Revolving Loan and Wells Term Loan bore interest based on separate predetermined pricing grids that allowed us to choose between base rate loans or LIBOR rate loans. Additionally, the Wells ABL required us to pay a quarterly unused credit commitment fee.

Lion Term Loan

Our subsidiary, Lion Oil, had a term loan credit facility with Fifth Third Bank, as administrative agent, and a syndicate of lenders, which, as amended and restated, had a total loan size of $275.0 million (the "Lion Term Loan"). This facility was extinguished in connection with the Refinancing on March 30, 2018. Interest on the unpaid balance of the Lion Term Loan was computed at a rate per annum equal to LIBOR or a base rate, at our election, plus the applicable margins, subject in each case to an all-in interest rate floor of 5.50% per annum.

Alon Partnership

Revolving Credit Facility

Alon USA, LP, a wholly-owned subsidiary of the Alon Partnership had a $240.0 million asset-based revolving credit facility with Israel Discount Bank of New York, as administrative agent (the “Alon Partnership Credit Facility”). This facility was extinguished in connection with the Refinancing on March 30, 2018. Borrowings under the Alon Partnership Credit Facility bore interest at LIBOR or base rate, at our election, plus the applicable margins.

Partnership Term Loan Credit Facility

The Alon Partnership had a $250.0 million term loan with Credit Suisse AG, as administrative agent (the “Alon Partnership Term Loan”). This term loan was extinguished in connection with the Refinancing on March 30, 2018. The Alon Partnership Term Loan bore interest at a rate per annum equal to LIBOR (subject to a floor of 1.25%) or a base rate plus the applicable margins.

Alon Term Loan Credit Facilities

Alon Energy Term Loan

Alon had a promissory note to Bank Hapoalim B.M. in an original principal amount of $38.0 million ("New Alon Energy Term Loan"). The New Alon Energy Term Loan was extinguished in connection with the Refinancing on March 30, 2018. The New Alon Energy Term Loan incurred interest at an annual rate equal to LIBOR plus an applicable margin.

Alon Asphalt Term Loan

Alon had a term loan owed to Export Development Canada secured by liens on certain of our asphalt terminals (“Alon Asphalt Term Loan”) in an original principal amount of $35.0 million. This loan was prepaid on March 29, 2018 in connection with the Refinancing on March 30, 2018. The Alon Asphalt Term Loan bore interest at a rate equal to LIBOR plus an applicable margin.

Alon Retail Credit Agreement

Alon wholly-owned subsidiaries Southwest Convenience Stores, LLC and Skinny’s LLC, (collectively, “Alon Retail”), had a credit agreement (“Alon Retail Credit Agreement”), that was to mature in March 2019, with Wells Fargo Bank, National Association, as administrative agent. This credit agreement was extinguished in connection with the Refinancing on March 30, 2018. The Alon Retail Credit Agreement included a term loan in an original principal amount of $110.0 million and a $10.0 million revolving credit facility. Borrowings under the Alon Retail Credit Agreement bore interest at LIBOR or base rate, at our election, plus an applicable margin, determined quarterly based upon Alon Retail’s leverage ratio.

Interest-Rate Derivative Instruments

Effective with the Delek/Alon Merger, we assumed Alon's interest rate swap agreements that were to mature in March 2019, which effectively fixed the variable LIBOR interest component of the term loans within the Alon Retail Credit Agreement. These interest rate swap agreements were terminated in connection with the Refinancing on March 30, 2018. These interest rate swaps were accounted for as cash flow hedges. See Note 11 for further information regarding the interest rate swap agreements.

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 the exposure to price fluctuations of commodity inventory above or below target levels at each of our segments;

• managing our exposure to commodity price risk associated with the purchase or sale of crude oil, feedstocks and finished grade fuel products at each of our segments;

• managing the cost of our credits for commitments required by the U.S. Environmental Protection Agency ("EPA") to blend biofuels into fuel products ("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 borrowings.

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 swap agreements, to achieve these objectives. Futures contracts are standardized agreements, traded on a futures exchange, to buy or sell the commodity at a predetermined price at a specified future date. Options provide the right, but not the obligation to buy or sell the commodity at a specified price in the future. Commodity swap 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 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.

During the first quarter of 2018, we utilized interest rate swap agreements to hedge floating rate debt by exchanging interest rate cash flows, based on a notional amount from a floating rate to a fixed rate. Effective with the Delek/Alon Merger, we had four interest rate swap agreements (that had maturities in March 2019) which effectively fixed the variable LIBOR interest component of the term loan within the Alon Retail Credit Agreement. The aggregate notional amount under these agreements were to cover approximately 77% of the outstanding principal of these term loans throughout the duration of the interest rate swaps. These interest rate swap agreements were terminated due to the extinguishment of the Alon Retail Credit Agreement in connection with the Refinancing on March 30, 2018, resulting in a reclassification of unrealized loss of $0.6 million from accumulated other comprehensive income to interest expense on the condensed consolidated statements of income during the three months ended March 31, 2018.

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 normal purchases and normal sales pursuant to ASC 815 and are not accounted for as derivative instruments. Rather, such forward contracts are accounted for under other applicable GAAP. Forward contracts entered into for trading purposes that do not meet the normal purchases, normal sales exception are accounted for as derivative instruments at fair value with changes in fair value recognized in earnings in the period of change. As of and for the three and six months ended June 30, 2019 and the year ended December 31, 2018, all of our forward contracts that were accounted for as derivative instruments consisted of contracts related to our Canadian crude trading operations. Since Canadian crude trading activity is not related to managing supply or pricing risk of inventory that will be used in production, such unrealized and realized gains and losses are recognized in other operating income, net rather than cost of materials and other on the accompanying condensed consolidated statements of income.

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 RIN 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 RIN commitment contracts are recorded in cost of materials and other on the condensed 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 and our interest rate agreements have been designated as cash flow hedges and the change in fair value between the execution date and the end of period (or early termination date in regards to the four Alon retail interest rate swaps discussed above) has been recorded in other comprehensive income. The fair value of these contracts is recognized in income 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 June 30, 2019 and December 31, 2018. 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 condensed consolidated balance sheets.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Delek applies the provisions of ASC 820, Fair Value Measurements ("ASC 820"), which defines fair value, establishes a framework for its measurement and expands disclosures about fair value measurements. ASC 820 requires disclosures that categorize 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.

Commodity swaps, exchange-traded futures, options, physical commodity forward purchase and sale contracts (that do not qualify as normal purchases or normal sales), and interest rate swaps are generally valued using industry-standard models that consider various assumptions, including quoted forward prices, spot prices, interest rates, time value, volatility factors and contractual prices for the underlying instruments, as well as other relevant economic measures. The degree to which these inputs are observable in the forward markets determines the classification as Level 2 or 3. Our contracts are valued based on exchange pricing and/or price index developers such as Platts or Argus and are, therefore, classified as Level 2. Commodity investments are valued using published market prices of the commodity on the applicable exchange and are, therefore, classified as Level 1.

Our Environmental Credits Obligation surplus or deficit is based on the amount of RINs or other emissions credits we must purchase, net of amounts internally generated and purchased and the price of those RINs or other emissions credits as of the balance sheet date, by refinery/obligor. The Environmental Credits Obligation surplus or deficit is categorized as Level 2, and is measured at fair value either directly through observable inputs or indirectly through market-corroborated inputs.

In March 2018, the El Dorado refinery received approval from the EPA for a small refinery exemption from the requirements of the renewable fuel standard for the 2017 calendar year, which resulted in a reduction of our RINs Obligation and related cost of materials and other of approximately $59.3 million for the six months ended June 30, 2018. In March 2018, the Krotz Springs refinery received such approval for 2017 as well, which resulted in a reduction of our RINs Obligation and related cost of materials and other of approximately $31.6 million for the six months ended June 30, 2018.

Our RIN 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 RINs Obligation. These RIN commitment contracts are categorized as Level 2, and are measured at fair value based on quoted prices from an independent pricing service. Changes in the fair value of these future RIN commitment contracts are recorded in cost of materials and other on the condensed consolidated statements of income.

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. As of and for the six months ended June 30, 2019 and 2018, 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. Our J. Aron step-out liability was categorized as Level 2, and measured at fair value using market prices for the consigned crude oil and refined products we were required to repurchase from J. Aron at the end of the term of the Supply and Offtake Agreement prior to the December 2018/January 2019 amendments to each of the Supply and Offtake Agreements. The J. Aron step-out liability was presented in the Obligation under Supply and Offtake Agreement line item of our condensed consolidated balance sheets. Gains (losses) related to the change in fair value was recorded as a component of cost of materials and other in the condensed consolidated statements of income. With respect to the amended Supply and Offtake Agreements, such amendments being effective December 2018 for our Big Spring Agreement and January 2019 for our El Dorado and Krotz Springs Agreements, we apply fair value measurement as follows: (1) we determine fair value for our amended fixed-price step-out liability based on changes in fair value related to interest rate risk where such obligation is categorized as Level 2 and is presented in the current or long-term portion, based on maturity of the agreement, of the Obligation under Supply and Offtake Agreements on our condensed consolidated balance sheets, and where gains (losses) related to changes in fair value are recorded as a component of interest expense in the condensed consolidated statements of income; and (2) we determine fair value of the short-term commodity-indexed financing facility 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 condensed consolidated balance sheets, and where gains (losses) related to the change in fair value are recorded as a component of cost of materials and other in the condensed consolidated statements of income.

Commodity investments represent those commodities (generally crude oil) physically on hand as a result of trading activities with physical forward contracts. Such investment stores are maintained on a weighted average cost basis for determining realized gains and losses on physical sales under forward contracts, and ending balances are adjusted to fair value at each reporting date. The unrealized loss on commodity investments for the three and six months ended June 30, 2019 totaled $1.0 million and $2.0 million, respectively.

The fair value hierarchy for our financial assets and liabilities accounted for at fair value on a recurring basis was as follows (in millions):

The derivative values above are based on analysis of each contract as the fundamental unit of account as required by ASC 820. 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 June 30, 2019 and December 31, 2018, $0.5 million and $0.4 million, respectively, of cash obligation was held by counterparty brokerage firms and has been netted with the net derivative positions with each counterparty.

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 2014, 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 is included as of June 30, 2019 in accrued expenses and other current liabilities on the accompanying condensed consolidated balance sheet, and which reflects a $5.7 million increase in the accrual recorded during the three months ended June 30, 2019. Additionally, through June 30, 2019, we have incurred $1.2 million of related legal expenses, $1.0 million and $1.1 million of which was incurred during the three and six months ended June 30, 2019, respectively, and has been recorded in general and administrative expenses in the accompanying condensed consolidated statements of income.

As of June 30, 2019 and December 31, 2018, AltAir (one of the California Discontinued Entities) was the party to a lawsuit whereby the plaintiff alleged breach of contract relating to a supply agreement during the period prior to the Delek/Alon Merger. We recorded a contingent liability associated with this matter (the "Ten-Tex Litigation") totaling $5.0 million as part of the purchase price allocation, which was finalized in June 2018. In July 2019, we reached a settlement with the plaintiff, whereby we are obligated for $2.3 million of the judgment against AltAir. Additionally, we believe that it's probable that the plaintiff will be successful in recovering a portion of its legal fees, and have estimated this liability to be approximately $0.3 million. Because the settlement was reached prior to the issuance of these consolidated financial statements, we have reduced our litigation accrual by $2.4 million during the three and six months ended June 30, 2019, which has been recorded in loss from discontinued operations (See Note 7).

Self-insurance

Delek records a self-insurance accrual for workers’ compensation claims up to a $1.0 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 $1.0 million deductible on a per accident basis for claims incurred in recent periods, and up to a $4.0 million deductible for remaining claims from certain prior periods.

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, the Occupational Safety and Health Administration, 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.

The Big Spring refinery has been negotiating an agreement with the EPA for over 10 years under the EPA’s National Petroleum Refinery Initiative regarding alleged historical violations of the federal Clean Air Act related to emissions and emissions control equipment. A Consent Decree resolving these alleged historical violations for the Big Spring refinery was lodged with the United States District Court for the Northern District of Texas on June 6, 2017. An amendment to the Consent Decree was agreed upon by Delek and the EPA/ United States Department of Justice (the "DOJ"), in late 2018 and was executed by Delek. The amended Consent Decree was lodged during the first quarter of 2019, and was entered by the Court on June 5, 2019. The civil penalty of $0.5 million was paid on June 18, 2019. Per the Consent Decree, the Company will be required to expend capital for pollution control equipment that may be significant over the next 10 years.

As of June 30, 2019, we have recorded an environmental liability of approximately $142.3 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, which were already being performed by the former operators of the refineries and terminals prior to our acquisition of those facilities, for known contamination of soil and groundwater, as well as estimated costs for additional issues which have been identified subsequent to the acquisitions. Approximately $3.7 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.

Crude Oil Releases

We have experienced several crude oil releases involving our assets, including four releases that occurred in the first quarter of 2019, three releases that occurred in the first quarter of 2018, and three releases that occurred in the fourth quarter of 2018. Cleanup operations and site maintenance and remediation efforts on these and other releases have been substantially completed. Confirmatory sampling is currently underway. We expect regulatory closure by the end of 2019. There were no significant spills in the second quarter of 2019.

Many of the releases have occurred on the SALA Gathering System. Currently, we are in the process of decommissioning certain sections of the SALA Gathering System in an effort to improve the safety and integrity of the system. We do not expect for the decommissioning of certain gathering lines on the system to have a material effect on the operational capabilities of the system.

The DOJ, on behalf of the EPA, and the State of Arkansas, on behalf of the Arkansas Department of Environmental Quality, have been pursuing an enforcement action against Delek Logistics with regard to potential violations of the Clean Water Act and certain state laws arising from the release of crude oil from a pumping facility at its Magnolia Station near the El Dorado Refinery ( the "Magnolia Release") since June 2015. On July 13, 2018, the DOJ and the State of Arkansas filed a civil action against two of Delek Logistics’ wholly-owned subsidiaries, Delek Logistics Operating LLC and SALA Gathering Systems LLC, in the United States District Court for the Western District of Arkansas.

In December 2018, Delek, the Unites States and the state of Arkansas reached an agreement to settle the claims related to the Magnolia Release for $2.2 million and the claims against Delek Logistics were resolved and an additional demand for a compliance audit at the Magnolia terminal was abandoned pursuant to payment of monetary penalties and other relief. As of June 30, 2019, we have accrued $2.2 million for the Magnolia Release. We believe this amount is adequate to cover our expected obligations related to these proceedings. The accrual is recorded in accrued expenses and other current liabilities in our condensed consolidated balance sheet. In July 2019, Delek signed and

submitted to the DOJ, a consent decree (the "Magnolia Consent Decree") to settle the release.  We expect the Magnolia Consent Decree to be finalized and to settle the accrual in the second half of 2019.

Letters of Credit

As of June 30, 2019, we had in place letters of credit totaling approximately $267.2 million with various financial institutions securing obligations primarily with respect to our commodity purchases for the refining segment and certain of our insurance programs. There were no amounts drawn by beneficiaries of these letters of credit at June 30, 2019.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

Under ASC 740, Income Taxes (“ASC 740”), companies are required to apply an estimated annual tax rate to interim period results on a year-to-date basis; however, the estimated annual tax rate should not be applied to interim financial results if a reliable estimate cannot be made.  In this situation, the interim tax rate should be based on actual year-to-date results.  We used an estimated annual tax rate to record income taxes for the three and six months ended June 30, 2019 and June 30, 2018.

For the three and six months ended June 30, 2018, we recorded additional income tax expense of $10.0 million and $2.6 million, respectively as a component of income tax expense from continuing operations related to the continued assessment of the tax effects of the 2017 Tax Cuts and Jobs Act ("Tax Reform Act"). This adjustment to the previously recorded provisional amounts include the tax effects on the remeasurement of the existing net deferred tax liabilities. We also had a reclassification of $1.6 million from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Reform Act, which was recorded during the first quarter of 2018.

Our effective tax rate was 22.5% and 22.8% for the three and six months ended June 30, 2019, respectively, compared to 27.3% and 23.3% for the three and six months ended June 30, 2018, respectively. The change in our effective tax rate was primarily due to the following discrete adjustments that were reported in the first and second quarters of 2018: further remeasurement of deferred tax assets and liabilities to properly account for the effects of the Tax Reform Act under Staff Accounting Bulletin 118; tax benefit for federal tax credits attributable to the Company's biodiesel blending operations for 2017 that have not been extended by Congress; tax expense associated with the impairment of assets held for sale; and changes in valuation allowance attributable to the book-tax basis differences from the Big Spring Logistic Asset Acquisition (See Note 5).

In addition, we entered into an agreement with the International Union of Operating Engineers (the "Union") to extend the Union agreement to March 31, 2022, and to freeze Alon's qualified pension plan for union employees effective July 31, 2018. 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, where payments are contingent upon continued employment at each annual payment date. The payments, the first of which was made in July 2018, are expected to total approximately $6.9 million in the aggregate without considering forfeitures (which cannot yet be estimated). The related expense has been or will be recognized over the remaining union contract period as follows (estimated without considering forfeitures): approximately $1.0 million during the six months ended June 30, 2019 and approximately $1.0 million for the remainder of 2019; approximately $2.0 million during each of the years 2020 and 2021, and approximately $0.1 million in 2022. In addition during the fourth quarter of 2018, we spun off a portion of the Alon's qualified pension plan into a new plan for Union employees - The Alon USA Pension Plan for Collective Bargained 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 the projected benefit obligation (the "Projected Benefit Obligation") which is the present value of benefits earned to date by plan participants, including the effect of assumed future salary increases.

Our estimated contributions to our pension plans during 2019 have not changed significantly from amounts previously disclosed in the notes to the consolidated financial statements for the year ended December 31, 2018. For the three and six months ended June 30, 2019, we made no contributions to our funded qualified pension plan and made contributions of $0.1 million related to payments to participants in our unfunded pension plans for the six months ended June 30, 2019, none of which were made in the second quarter of 2019.

Leases [Abstract]

Leases

Leases

We lease certain retail stores, land, building and various equipment. 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 to 15 years or more. The exercise of existing lease renewal options is at our sole discretion. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

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 stores and crude storage equipment.

As of June 30, 2019, $30.0 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.

Dividend Declaration

On July 29, 2019, our Board of Directors voted to declare a quarterly cash dividend of $0.29 per share of our common stock, payable on September 3, 2019 to shareholders of record on August 19, 2019.

Settlement of Litigation

In July 2019, we reached a settlement on the Ten-Tex Litigation (see Note 13) related to one of the California Discontinued Entities that resulted in a reduction in our contingent loss accrual totaling $2.4 million, resulting in a remaining obligation (inclusive of an estimate for our obligation for plaintiff legal fees) of $2.6 million. Such reduction has been recorded in loss from discontinued operations on the accompanying consolidated statements of operations for the three and six months ended June 30, 2019. See Notes 7 and 13 for further discussion.

Investment in Pipeline Joint Venture

On July 30, 2019, we, through our wholly-owned direct subsidiary Delek US Energy, Inc. (“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 will have a 15% ownership interest in WWP. 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) and it is anticipated that Delek Energy’s capital contributions will total approximately $340 million to $380 million over the course of construction (expected to be two to three years), with an initial capital contribution of $40.0 million due within 30 days of the execution of the LLCA.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting

Our condensed consolidated financial statements include the accounts of Delek and its subsidiaries. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted, although management believes that the disclosures herein are adequate to make the financial information presented not misleading. Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP applied on a consistent basis with those of the annual audited consolidated financial statements included in our Annual Report on Form 10-K as amended and filed with the Securities and Exchange Commission ("SEC") on June 27, 2019 (the "Annual Report on Form 10-K") and in accordance with the rules and regulations of the SEC. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2018 included in our Annual Report on Form 10-K.

Consolidation of Variable Interest Entity

Our condensed consolidated financial statements include Delek Logistics Partners, LP ("Delek Logistics"), which is a variable interest entity. 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.

Consolidation

In the opinion of management, all adjustments necessary for a fair presentation of the financial condition and the results of operations for the interim periods have been included. All significant intercompany transactions and account balances have been eliminated in consolidation. All adjustments are of a normal, recurring nature. Operating results for the interim period should not be viewed as representative of results that may be expected for any future interim period or for the full year.

Reclassifications

Certain prior period amounts have been reclassified in order to conform to the current period presentation.

New Accounting Pronouncements

New Accounting Pronouncements Adopted During 2019

Accounting Standards Update ("ASU") 2016-02, Leases

In February 2016, the Financial Accounting Standards Board (the "FASB") issued guidance that requires the recognition of a lease liability and a right-of-use asset, initially measured at the present value of the lease payments, in the statement of financial condition for all leases with terms longer than one year. The guidance was subsequently amended to consider the impact of practical expedients and provide additional clarifications. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. We adopted the new lease standard on January 1, 2019. We elected the package of practical expedients which, among other things, allows us to carry forward the historical lease classification. For certain lease classes, we have elected the practical expedient not to separate lease and non-lease components, which allows us to combine the components if certain criteria are met. Further, we elected the optional transition method, which allows us to recognize a cumulative-effect adjustment to the opening balance sheet of retained earnings at the date of adoption and to not recast our comparative periods. We have not elected the hindsight practical expedient, which would have allowed us to use hindsight in determining the reasonably certain lease term. The adoption of the lease accounting guidance had no impact on January 1, 2019 retained earnings and resulted in the recognition of a $211.0 million lease liability and a corresponding right-of-use asset on our consolidated balance sheet. The adoption did not have a material impact on our consolidated income statement. See Note 20 for further information.

ASU 2017-12, Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities

In August 2017, the FASB issued guidance to better align financial reporting for hedging activities with the economic objectives of those activities for both financial (e.g., interest rate) and commodity risks. The guidance was intended to create more transparency in the presentation of financial results, both on the face of the financial statements and in the footnotes, and simplify the application of hedge accounting guidance. This guidance is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Companies are required to apply the guidance on a modified retrospective transition method in which the cumulative effect of the change is recognized within equity in the consolidated balance sheet as of the date of adoption. We adopted this guidance on January 1, 2019 and the adoption did not have a material impact on our business, financial condition or results of operations. See Note 11 for further information.

Accounting Pronouncements Not Yet Adopted

ASU 2018-15, Intangible - Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract

In August 2018, the FASB issued guidance related to customers’ accounting for implementation costs incurred in a cloud computing arrangement that is considered a service contract. This pronouncement aligns the requirements for capitalizing implementation costs in such arrangements with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued. Entities can choose to adopt the new guidance prospectively or retrospectively. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition and results of operations.

ASU 2018-14, Compensation - Changes to the Disclosure Requirements for Defined Benefit Plans

In August 2018, the FASB issued guidance related to disclosure requirements for defined benefit plans. The pronouncement eliminates, modifies and adds disclosure requirements for defined benefit plans. The pronouncement is effective for fiscal years ending after December 15, 2020, and early adoption is permitted. We expect to adopt this guidance on or before the effective date and do not expect adopting this new guidance will have a material impact on our business, financial condition or results of operations.

ASU 2018-13, Fair Value Measurement - Changes to the Disclosure Requirements for Fair Value Measurement

In August 2018, the FASB issued guidance related to disclosure requirements for fair value measurements. The pronouncement eliminates, modifies and adds disclosure requirements for fair value measurements. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2019, with early adoption permitted. We expect to adopt this guidance on or before the effective date and do not expect adopting this new guidance will have a material impact on our business, financial condition or results of operations.

ASU 2016-13, Financial Instruments - Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued guidance requiring the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Organizations will now use forward-looking information to better inform their credit loss estimates. This guidance is effective for interim and annual periods beginning after December 15, 2019. We expect to adopt this guidance on or before the effective date and are currently evaluating the impact that adopting this new guidance will have on our business, financial condition and results of operations.

Segment Reporting [Abstract]

Segment Reporting, Policy

We aggregate our operating units 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 consist of the following: our corporate activities; results of certain immaterial operating segments, including our Canadian crude trading operations (as discussed in Note 11); Alon's asphalt terminal operations acquired as part of the Delek/Alon Merger and subsequently substantially disposed in the second quarter of 2018 (see Note 7 for further discussion); the California Discontinued Entities which were acquired as part of the Delek/Alon Merger and subsequently disposed over the first seven months of 2018 (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. Segment contribution margin is defined as net revenues less cost of materials and other and operating expenses, excluding depreciation and amortization.

Property, Plant and Equipment, Policy

In accordance with Accounting Standards Codification ("ASC") 360, Property, Plant and Equipment ("ASC 360"), Delek evaluates the realizability of property, plant and equipment as events occur that might indicate potential impairment.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments, Policy [Policy Text Block]

Delek applies the provisions of ASC 820, Fair Value Measurements ("ASC 820"), which defines fair value, establishes a framework for its measurement and expands disclosures about fair value measurements. ASC 820 requires disclosures that categorize 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.

Such intercompany notes and right of use assets are eliminated from total consolidated assets in Corporate, Other and Eliminations.

⁽²⁾  Refining segment and consolidated net revenues and cost of materials and other for the quarter and six months ended June 30, 2018 reflect a correction of an intercompany elimination which resulted in an increase in those accounts of $73.4 million not previously reflected on the unaudited consolidated financial statements in our June 30, 2018 Quarterly Report on Form 10-Q filed on August 9, 2018. Such amounts are not considered material to the financial statements and had no impact to operating income or segment contribution margin for those periods.

[1] Refining segment and consolidated net revenues and cost of materials and other for the quarter and six months ended June 30, 2018 reflect a correction of an intercompany elimination which resulted in an increase in those accounts of $73.4 million not previously reflected on the unaudited consolidated financial statements in our June 30, 2018 Quarterly Report on Form 10-Q filed on August 9, 2018. Such amounts are not considered material to the financial statements and had no impact to operating income or segment contribution margin for those periods.
