[2] The information presented includes the results of operations of the Logistics Assets Predecessor. Prior to the El Dorado Offloading Racks Acquisition and the Tyler Crude Tank Acquisition, the Logistics Assets Predecessor did not record revenues for intercompany throughput and storage services. See Notes 1 and 2 for further discussion.

[3] There were no revenues or expenses associated with the Tyler Assets Predecessor included in our condensed consolidated financial statements for the three months ended March 31, 2014 as the Tyler Assets were not fully constructed and were not placed into service until January 2015.

[5] Cash distributions include $61.9 million in cash payments for the El Dorado Offloading Racks Acquisition and the Tyler Crude Tank Acquisition. As an entity under common control with Delek, we record the assets that we acquire from Delek on our balance sheet at Delek's historical book basis instead of fair value. Additionally, any excess of cash paid over the historical book basis of the assets acquired from Delek is recorded within equity. As a result of the El Dorado Offloading Racks Acquisition and the Tyler Crude Tank Acquisition, our equity balance decreased $42.7 million during the three months ended March 31, 2015.
