Acquisitions	Acquisitions Trucking Assets Acquisition Effective May 1, 2020, the Partnership, through its wholly-owned subsidiary DKL Transportation, LLC, acquired Delek Trucking, LLC consisting of certain leased and owned tractors and trailers and related assets from Delek Holdings. The total consideration was approximately $48.0 million in cash. We financed this acquisition with a combination of cash on hand and borrowings under the DKL Credit Facility (as defined in Note 7). The Trucking Assets are recorded in our pipelines and transportation segment and include approximately 150 trucks and trailers, which are primarily leased or owned, respectively. In connection with the closing of the transaction, Delek Holdings, the Partnership and various of their respective subsidiaries entered into a Transportation Services Agreement (the “Trucking Assets TSA Agreement”). Under the Trucking Assets TSA Agreement, the Partnership will gather, coordinate pickup of, transport and deliver petroleum products for Delek Holdings, as well as provide ancillary services as requested. The transaction and related agreements were approved by the Conflicts Committee of the Partnership's general partner, which is comprised solely of independent directors. See Note 3 for more detailed descriptions of these agreements. The Trucking Assets Acquisition was considered a transaction between entities under common control. Accordingly, the Trucking Assets were recorded at amounts based on Delek Holdings' historical carrying value as of the acquisition date. The carrying value of the Trucking Assets as of the acquisition date was $13.3 million, consisting of $0.5 million of owned assets and $12.8 million Right of Use asset for leased assets. The Right of Use asset offsets with an equivalent operating lease liability. Prior periods have not been recast as these assets do not constitute a business in accordance with Accounting Standard Update 2017-01, Clarifying the Definition of a Business ("ASU 2017-01"). We capitalized approximately $0.3 million of acquisition costs related to the Trucking Assets Acquisition. Big Spring Gathering Assets Acquisition Effective March 31, 2020, the Partnership, through its wholly-owned subsidiary DKL Permian Gathering, LLC, acquired the Big Spring Gathering Assets from Delek Holdings, located in Howard, Borden and Martin Counties, Texas. The total consideration was subject to certain post-closing adjustments and was comprised of $100.0 million in cash and 5.0 million of our common limited partner units (the "Additional Units"). We financed the cash component of this acquisition with borrowings from the DKL Credit Facility. The Big Spring Gathering Assets are recorded in our pipelines and transportation segment and include: •Crude oil pipelines; •Approximately 200 miles of gathering systems; •Approximately 65 Tank battery connections; •Terminals (total storage of approximately 650,000 bbls); and •Applicable rights-of-way. In connection with the closing of the transaction, Delek Holdings, the Partnership and various of their respective subsidiaries entered into a Throughput and Deficiency Agreement (the “Big Spring T&D Agreement”). Under the Big Spring T&D Agreement, the Partnership will operate and maintain the Big Spring Gathering Assets connecting Delek Holdings' interests in and to certain crude oil with the Partnership's Big Spring, Texas terminal and provide gathering, transportation and other related services with respect to any and all crude produced from shipper’s and certain other producers’ respective interests for delivery at the Big Spring Terminal. The transaction and related agreements were approved by the Conflicts Committee of the Partnership's general partner, which is comprised solely of independent directors. See Note 3 for more detailed descriptions of these agreements. The Big Spring Gathering Assets Acquisition was considered a transaction between entities under common control. Accordingly, the Big Spring Gathering Assets were recorded at amounts based on Delek Holdings' historical carrying value as of the acquisition date. The carrying value of the Big Spring Gathering Assets as of the acquisition date was $209.5 million. Pursuant to the common control guidance, the 5.0 million units issued (which had a closing market price of $9.10 per unit on the transaction date) were recorded in equity at $109.5 million, representing the net carrying value of the Big Spring Gathering Assets purchased of $209.5 million less the $100.0 million cash consideration. Prior periods have not been recast as these assets do not constitute a business in accordance with ASU 2017-01. We capitalized approximately $0.7 million of acquisition costs related to the Big Spring Gathering Assets Acquisition. Big Spring Logistics Assets Acquisition Effective March 1, 2018, the Partnership, through its wholly-owned subsidiary DKL Big Spring, LLC, acquired the Big Spring Logistics Assets from Delek Holdings, which are primarily located at or adjacent to the Big Spring Refinery. The total purchase price was $170.8 million, financed through borrowings under the Partnership’s revolving credit facility.

In connection with the closing of the transaction, Delek Holdings, the Partnership and various of their respective subsidiaries entered into and amended certain existing contracts, including entering into new pipelines, storage and throughput facilities and asphalt services agreements. The transaction and related agreements were approved by the Conflicts Committee of the Partnership's general partner, which is comprised solely of independent directors. See Note 4 for more detailed descriptions of these agreements. The Big Spring Logistics Assets Acquisition was considered a transaction between entities under common control. Accordingly, the Big Spring Logistics Assets were recorded at amounts based on Delek Holdings' historical carrying value as of the acquisition date. The excess of the cash paid over the historical carrying value of the assets acquired from Delek Holdings amounted to $98.8 million and was recorded as a reduction in equity. The historical carrying value of the Big Spring Logistics Assets as of the acquisition date was $72.0 million, which is net of $0.8 million of assumed asset retirement obligations. Prior periods have not been recast, as these assets did not constitute a business in accordance with ASU 2017-01. We capitalized approximately $0.4 million of acquisition costs related to the Big Spring Logistics Assets Acquisition. Marketing Contract Intangible Acquisition Additionally, concurrent with the Big Spring Logistics Assets Acquisition, Delek Holdings, the Partnership and various of their respective subsidiaries entered into a new marketing agreement, whereby the Partnership markets certain refined products produced at or sold from the Big Spring Refinery to various customers in return for a marketing fee (the "Marketing Contract Intangible Acquisition"). We recorded a related contract intangible asset in the amount of $144.2 million based on the amount paid to enter into the contract, which represents the fair value of the intangible asset. The contract intangible asset is amortized over a twenty year period as a component of net revenues from affiliates. The total consideration paid was financed through borrowings under the Partnership's revolving credit facility. This transaction and related marketing agreement were approved by the Conflicts Committee of the board of the Partnership's general partner, which is comprised solely of independent directors.
