[1] | The Credit Facility and Vessel financing Newbuildings carry a floating LIBOR interest rate, plus a margin and the fair value is assumed to equal the carrying value.
[2] | Vessels measured at fair value were includes as part of the Vessels balance of $935.8 million in our consolidated balance sheet as of December 31, 2017
[3] | Goodwill was written down to zero as of December 31, 2017. The most important assumptions and estimates applied by us in the goodwill impairment assessment included estimated future cash flows from our vessel operations, which is mainly driven by estimated daily time charter equivalents (TCE), operating expenses and the discount rate. The estimated future cash flows for revenues and operating expenses applied in the goodwill impairment model were aligned with the cash flows applied in the vessel impairment model.
