[1] We estimated the fair value of the Pullmantur reporting unit using a probability-weighted discounted cash flow model. The principal assumptions used in the discounted cash flow model are projected operating results, weighted-average cost of capital and terminal value. Significantly impacting these assumptions was the decision to reduce the size of Pullmantur's fleet. The discounted cash flow model used our 2016 projected operating results as a base. To that base we added future years’ cash flows through 2020 assuming multiple revenue and expense scenarios that reflect the impact of different global economic environments for this period on Pullmantur’s reporting unit. We assigned a probability to each revenue and expense scenario. We discounted the projected cash flows using rates specific to Pullmantur’s reporting unit based on its weighted-average cost of capital, which was determined to be 11%.
