General	General Organization As used in this report, the terms "Delek Logistics Partners, LP," the "Partnership," "we," "us," or "our" may refer to Delek Logistics Partners, LP, one or more of its consolidated subsidiaries or all of them taken as a whole. The Partnership is a Delaware limited partnership formed in April 2012 by Delek US Holdings, Inc. ("Delek Holdings") and its subsidiary Delek Logistics GP, LLC, our general partner (our "general partner'). Effective March 1, 2018, the Partnership, through its wholly-owned subsidiary DKL Big Spring, LLC, acquired from Delek Holdings certain logistics assets primarily located at or adjacent to Delek Holdings' refinery near Big Spring, Texas (the "Big Spring Refinery") and Delek Holdings' light products distribution terminal located in Stephens County, Oklahoma (collectively, the "Big Spring Logistic Assets" and such transaction the "Big Spring Logistic Assets Acquisition"). See Note 3 for further information regarding the Big Spring Logistic Assets Acquisition. Description of Business The Partnership primarily owns and operates logistics and marketing assets for crude oil and intermediate and refined products. A substantial majority of our existing assets are integral to and dependent on the success of Delek Holdings’ refining and marketing operations. We gather, transport and store crude oil and market, wholesale market, distribute, transport and store refined products in select regions of the southeastern United States and west Texas for Delek Holdings and third parties. The Partnership generates revenue by charging fees for gathering, transporting, offloading and storing crude oil and for marketing, wholesale marketing, distributing, transporting and storing refined products. A substantial majority of our contribution margin, which we define as net revenues less cost of materials and other and operating expenses, excluding depreciation and amortization, is derived from commercial agreements with Delek Holdings with initial terms ranging from five to ten years.
