The equity in earnings of White Cliffs for the three months and six months ended June 30, 2016 and 2015 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. Such expenses are recorded by White Cliffs and are allocated to our ownership interest. White Cliffs recorded $0.4 million and $0.4 million of such general and administrative expense for the three months ended June 30, 2016 and 2015, respectively. White Cliffs recorded $0.9 million and $0.7 million of such general and administrative expense for the six months ended June 30, 2016 and 2015, respectively.

The members of White Cliffs are required to contribute capital to White Cliffs to fund various projects. For the six months ended June 30, 2016, we contributed $2.2 million for an expansion project that added approximately 65,000 barrels per day of capacity.

NGL Energy Partners LP

At June 30, 2016, we no longer own common units representing limited partner interests in NGL Energy Partners LP (NYSE: NGL) ("NGL Energy"). On April 27, 2016, we sold all of our NGL Energy limited partner units for $13.00 per unit and recorded a $9.1 million gain on disposal. We continue to hold an 11.78% interest in the general partner of 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. The information below pertains to our limited partner and general partner investments in NGL Energy.

See Note 4 for discussion of the other-than-temporary impairment of our common unit investment in NGL Energy.

Under the equity method, our policy is to record our equity in earnings of NGL Energy on a one-quarter lag, as we do not expect to have information on the earnings of NGL Energy in time to consistently record the earnings in the quarter in which they are generated.

During the three months ended December 31, 2015, NGL issued common units which diluted our limited partnership interest. 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. In the first quarter of 2015, NGL announced several transactions in which they issued common units publicly and privately which diluted our limited partnership interest. As we record activity on a one-quarter lag, we recognized a non-cash gain of $5.9 million associated with these issuances in the second quarter of 2015.

During the six months ended June 30, 2015, we sold 1,999,533 of our NGL Energy common units for $56.3 million, net of related costs of $0.5 million. We recorded net gains related to these sales of $6.6 million and $14.5 million in "other expense (income)" in our condensed consolidated statements of operations and comprehensive income (loss) for the three months and six months ended June 30, 2015.
