Dominion Energy Gas

Iroquois

Dominion Energy Gas' equity earnings totaled $11 million and $9 million for the six months ended June 30, 2017 and 2016, respectively. Dominion Energy Gas received distributions from this investment of $11 million for both the six months ended June 30, 2017 and 2016. At both June 30, 2017 and December 31, 2016, the carrying amount of Dominion Energy Gas' investment of $98 million exceeded its share of underlying equity in net assets by $8 million. The difference reflects equity method goodwill and is not being amortized. In May 2016, Dominion Energy Gas sold 0.65% of the non-controlling partnership interest in Iroquois to TransCanada Corporation for approximately $7 million, which resulted in a $5 million ($3 million after-tax) gain.
