	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017		2016

Our equity in earnings of White Cliffs for the three months and six months ended June 30, 2017 and 2016, is less than 51% of the net income of White Cliffs for the same periods. This is due to certain general and administrative expenses we incur in managing the operations of White Cliffs that the other owners are not obligated to share. In addition, our equity in earnings is also impacted by the elimination of earnings on commodity sales with White Cliffs. Revenue related to inventory transactions with White Cliffs is deferred until a sale of the inventory has been made with a third party.

The members of White Cliffs are required to contribute capital to White Cliffs to fund various projects. For the six months ended June 30, 2017, we contributed $1.4 million to White Cliffs related to capital projects.

Glass Mountain Pipeline, LLC

We own a 50% interest in Glass Mountain Pipeline, LLC (“Glass Mountain”), which we account for under the equity method. The excess of the recorded amount of our investment over the book value of our share of the underlying net assets represents equity method goodwill and capitalized interest at June 30, 2017. Capitalized interest is amortized as a reduction of earnings from equity method investments.

NGL Energy Partners LP

We own an 11.78% interest in the general partner of NGL Energy Partners LP (NYSE: NGL) (“NGL Energy”) which is being accounted for under the equity method in accordance ASC 323-30-S99-1, as our ownership is in excess of the 3 to 5 percent interest which is generally considered to be more than minor. The general partner of NGL Energy is not a publicly traded company.

Our policy is to record our equity in earnings of NGL Energy on a one-quarter lag, as we do not expect information on the earnings of NGL Energy to always be available in time to consistently record the earnings in the quarter in which they are generated. Accordingly, the equity in earnings from NGL Energy, which is reflected in our condensed consolidated statements of operations and comprehensive income (loss) for the three months and six months ended June 30, 2017 and 2016, relates to the earnings of NGL Energy for the three months and six months ended March 31, 2017 and 2016, respectively.

During the three months ended December 31, 2015, NGL issued common units which diluted our limited partnership interest, which we have since divested. As we record activity on a one-quarter lag, we recognized a non-cash loss of $41.0 thousand associated with these issuances for the six months ended June 30, 2016.
