[1] | The information presented includes the results of operations of the DKL Predecessor for periods presented through November 6, 2012 and of the Tyler Predecessor for all periods presented, and of the Partnership for the period beginning November 7, 2012, the date the Partnership commenced operations.
[2] | The information presented includes the results of operations of the Tyler Predecessor. Prior to the completion of the Tyler Acquisition, our Predecessor did not record revenues for intercompany gathering, pipeline transportation, terminalling and storage services.
[3] | Adjusted to include the historical results of the Tyler Terminal and Tank Assets. See Notes 1 and 3 for further discussion.
[4] | Net income for the year ended December 31, 2012 includes a one-time tax benefit of $18.5 million. The majority of the Partnership's deferred tax assets and liabilities relates to the Predecessor's conversion from a corporation to a partnership and as a result of such conversion we are not subject to federal income taxes. The conversion from a taxable corporation to a passthrough resulted in this one-time tax benefit.
[5] | Adjusted to include the historical cash flows of the Tyler Terminal and Tank Assets. See Notes 1 and 3 for further discussion.
