·                  Amendments to NGL’s revolving credit facility in November and December 2013 that expanded the capacity to $1.721 billion, extended the maturity date to late 2018, and reduced interest costs; and

·                  First issue of senior unsecured notes in the amount of $450 million in a private placement in October 2013.

Analysts, investors, and other interested parties may access the conference call by dialing (800) 706-7741 and providing access code 55877851.

NGL defines EBITDA as net income attributable to parent equity, plus income taxes, interest expense, loss on early extinguishment of debt, and depreciation and amortization expense. NGL defines Adjusted EBITDA as EBITDA excluding the unrealized gain or loss on derivative contracts, the gain or loss on the disposal or impairment of assets, and share-based compensation expense. For purposes of NGL’s Adjusted EBITDA calculation, NGL draws a distinction between unrealized gains and losses on derivatives and realized gains and losses on derivatives. During the period when a derivative contract is open, NGL records changes in the fair value of the derivative as unrealized gains or losses.  When a derivative contract is settled, NGL reverses the previously-recorded unrealized gain or loss and records a realized gain or loss.  The realized gain or loss is equal to the amount received or paid on the contract.  NGL acquired Gavilon Energy in December 2013.  NGL is still in the process of developing procedures to calculate realized and unrealized gains and losses for the Gavilon Energy operations in the same way NGL calculates them for its other operations.  Accordingly, the unrealized gain and loss in the Adjusted EBITDA table below excludes any unrealized gains and losses related to Gavilon Energy.

EBITDA and Adjusted EBITDA should not be considered an alternative to net income, income before income taxes, cash flows from operating activities, or any other measure of financial performance calculated in accordance with GAAP as those items are used to measure operating performance,

liquidity or the ability to service debt obligations. NGL believes that EBITDA provides additional information for evaluating its ability to make quarterly distributions to its unitholders and is presented solely as a supplemental measure. NGL believes that Adjusted EBITDA provides additional information for evaluating its financial performance without regard to its financing methods, capital structure and historical cost basis. Further, EBITDA and Adjusted EBITDA, as NGL defines them, may not be comparable to EBITDA and Adjusted EBITDA or similarly titled measures used by other entities. A reconciliation of Adjusted EBITDA to net income attributable to parent equity is shown below.
