(1) | The carrying value of our equity method investment is $2,814 million higher than the underlying equity in the net assets of the investee due to $2,868 million of equity method goodwill and $69 million in basis differences in AOCI, offset by $123 million due to a tax sharing liability to TTI under the tax sharing agreement.
(2) | The carrying value of our equity method investment is $12 million higher than the underlying equity in the net assets of the investee due to the remeasurement of our retained investment to fair value in 2014.
(3) | The carrying value of our equity method investment is $5 million higher than the underlying equity in the net assets of the investee due to guarantees, which we discuss below.
(4) | The carrying value of our equity method investment is $130 million higher than the underlying equity in the net assets of the investee due to equity method goodwill.
(5) | The carrying value of our equity method investment is $169 million lower than the underlying equity in the net assets of the investee due to an other-than-temporary impairment recorded in 2018.
(6) | The carrying value of our equity method investment is $31 million lower than the underlying equity in the net assets of the investee due to an other-than-temporary impairment recorded in 2018.
(7) | The carrying value of our equity method investment is $284 million and $237 million higher than the underlying equity in the net assets of the investee at December 31, 2018 and 2017, respectively, primarily due to guarantees, which we discuss below, and interest capitalized on the investment, as the JV has not commenced its planned principal operations.
