[1] | Losses are primarily attributable to our investment in Centennial. As a result of a trend in declining earnings, we estimated the fair value of this equity-method investment during each of the last three fiscal years. Our estimates, based on a combination of the market and income approaches, indicate that the fair value of this investment remains substantially in excess of its carrying value.
[2] | Our investments in unconsolidated affiliates classified within the Offshore Pipelines & Services segment were sold to Genesis in July 2015.

- Definition If the price paid to acquire an ownership interest exceeded the underlying book value of the capital accounts acquired, such excess cost amounts are included within the carrying values of the investments. These costs were attributable to the underlying tangible and amortizable intangible assets of certain unconsolidated affiliates, and are amortized as a reduction in equity earnings in a manner similar to depreciation. This represents the amortization of such excess cost amounts for the period. + References No definition available. + Details
