Goodwill [Abstract] |
Goodwill Disclosure [Text Block] | Goodwill Goodwill represents the excess of the aggregate purchase price over the fair value of the identifiable net assets acquired. Goodwill acquired in a business combination is recorded at fair value and is not amortized. Our goodwill relates to the west Texas assets contributed to us by Delek Marketing & Supply, LLC ("Delek Marketing"), a direct wholly owned subsidiary of Delek, in connection with our initial public offering (the "Offering") and to the purchase price allocation of certain of our third party acquisitions. We perform an annual assessment of whether goodwill retains its value. This assessment is done more frequently if indicators of potential impairment exist. We performed our annual goodwill impairment review in the fourth quarter of 2016, 2015 and 2014. We performed a discounted cash flows test, using a market participant weighted average cost of capital, and estimated minimal growth rates for revenue, gross profit and capital expenditures based on history and our best estimate of future forecasts. We also estimated the fair values using a multiple of expected future cash flows, such as those used by third party analysts. In 2016, 2015 and 2014, the annual impairment review resulted in the determination that no impairment of goodwill had occurred. Our goodwill accounts in our wholesale marketing and terminalling segment amounted to $7.5 million as of December 31, 2016, 2015 and 2014. Our goodwill accounts in our pipelines and transportation segment amounted to $4.7 million as of December 31, 2016 and 2015 and $4.2 million as of December 31, 2014. During the year ended December 31, 2015, we recorded goodwill of $0.5 million in our pipelines and transportation segment in connection with the acquisition of the FTT Assets.
